Recommendation: For novice Windows users, we highly recommend downloading a driver update tool like DriverDoc [Download DriverDoc - Product by Solvusoft] to help update your Prolific USB drivers. This driver update utility makes sure that you are getting the correct drivers for your CP Tech cp-us-03 and operating system version, preventing you from installing the wrong drivers.
CP Tech cp-us-03 errors can be rooted in an outdated or corrupted device driver. Device drivers fail intermittently and inexplicably without any apparent reason. The excellent thing is that even though your USB problem persists, you can fix it by installing the updated driver.
It is often hard to find a right solution to a CP Tech cp-us-03 hardware-related error by visiting Prolific's website. Although you might have plenty of experience in handling CP Tech cp-us-03 drivers, there still is a lot of time involved in this update process. Installing incorrect drivers may have an adverse impact on the functionality of your hardware or operating system.
There is a lot of work involved in updating device drivers, so we strongly suggest downloading and installing a driver update utility. A good driver update software will ensure you have the most recent and best driver so you're never left with a problem with your device again. Sustaining a driver backup file is an excellent feature that allows you to revert any driver back to a previous version, in the event that something catastrophic occurs.
If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter Prolific CP-US-03 into the search box above and then submit. In the results, choose the best match for your PC and operating system.
Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.
The actual number of CPUs that are used for RSS is also limited by the total number of core processors that remain after the RSS base CPU number has been configured. For example, if the administrator sets the maximum number of RSS CPUs on a quad-core computer system to 6, the networking driver stack uses, at most, 4 CPUs for RSS. If the administrator also sets the RSS base CPU number to 1, the networking driver stack uses at most 3 CPUs (CPU numbers 1, 2, and 3).
Most adapters in the Intel Ethernet 700 Series withSFP+/SFP28/QSFP+ cages have firmware that requires that Intelqualified modules are used; these qualified modules are listedbelow. This qualification check cannot be disabled by thedriver.
The sis(4) driver supports Silicon Integrated Systems SiS 900 andSiS 7016 based Fast Ethernet adapters and embedded controllers, aswell as Fast Ethernet adapters based on the National SemiconductorDP83815 (MacPhyter) and DP83816 chips. Supported adaptersinclude:
[amd64, i386] Lucent Technologies WaveLAN/IEEE 802.11b wirelessnetwork adapters and workalikes using the Lucent Hermes, IntersilPRISM-II, Intersil PRISM-2.5, Intersil Prism-3, and SymbolSpectrum24 chipsets (wi(4)driver)
A USB to serial adapter, also referred to as a USB serial converter or RS232 adapter is a small electronic device which can convert a USB signal to serial RS232 data signals. RS232 is the type of signal which is in many older PCs and is referred to as a serial COM port.
A USB to serial adapter typically converts between USB and either RS232, RS485, RS422 or TCP signals, however some USB to serial adapters have other special conversion features such as custom baud rates, high-speed or other.
Even the USB to serial adapter RS232 standard is an older communication protocol it is still used by many modern serial RS232 devices in both business and consumer markets and is also often used for personal and office serial devices.
More recently most new computers do not have a built-in COM port so a USB serial adapter is often used for connecting many types of serial devices to a computer. A standard USB to serial adapter is a very useful device for connecting equipment such as printers, scanners, scales and GPS devices, but also most business and consumer equipment can be connected to a computer by using an industrial grade adapter.
The USB serial adapter is made in different versions and grades, the 1-port adapter is very popular and one of the most commonly used adapters. Two to four port adapters are also frequently used if the user needs more than one serial port. Multi-port adapters can be connected to a computer by using just one USB cable, where after the computers operating system will create multiple virtual COM ports. Grades range from standard consumer grade to industrial grade and even mission critical grade adapters.
Most consumer grade USB serial adapters are not optically isolated or protected against high voltage spikes however most industrial grade adapters are optically isolated which means they are protected against voltage spikes and surges, ground-loops and most other voltages which potentially can damage the adapter or the connected serial devices.
We use the Silicon Labs CP2102 USB-to-UART Bridge Controller in several of our products to provide USB connectivity while communicating via a simple serial protocol. It is the key component of our Pololu USB-to-serial adapter:
Recent versions of the linux kernel include support for the CP2102 USB-to-UART Bridge Controller as part of the usb-serial driver, so your Pololu CP2102 should work right out of the box. We have verified that the CP2102 works with Ubuntu versions 7.04 and 8.04. If you experience any problems, we recommend you upgrade to the most recent version of your distribution.
To process received data efficiently, a miniport driver's receive interrupt service function schedules a deferred procedure call (DPC). Without RSS, a typical DPC indicates all received data within the DPC call. Therefore, all of the receive processing that is associated with the interrupt runs on the CPU where the receive interrupt occurs. For an overview of non-RSS receive processing, see Non-RSS Receive Processing.
With RSS, the NIC and miniport driver provide the ability to schedule receive DPCs on other processors. Also, the RSS design ensures that the processing that is associated with a given connection stays on an assigned CPU. The NIC implements a hash function and the resulting hash value provides the means to select a CPU.
Hash calculation with a single queue
The NIC calculates the hash value and the miniport driver assigns received packets to queues that are associated with CPUs. For more information, see RSS with a Single Hardware Receive Queue.
RSS provides a means to rebalance the network processing load between CPUs as host system load varies. To rebalance the load, overlying drivers can change the indirection table. For more information about specifying indirection tables, hash types, and hashing functions, see RSS Configuration.
RSS enables driver stacks to process send and receive-side data for a given connection on the same CPU. Typically, an overlying driver (for example, TCP) sends part of a data block and waits for an acknowledgment before sending the balance of the data. The acknowledgment then triggers subsequent send requests. The RSS indirection table identifies a particular CPU for the receive data processing. By default, the send processing runs on the same CPU if it is triggered by the receive acknowledgment. A driver can also specify the CPU (for example, if a timer is used).
The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver.
The CP210x Manufacturing DLL and Runtime DLL have been updated and must be used with v 6.0 and later of the CP210x Windows VCP Driver. Application Note Software downloads affected are AN144SW.zip, AN205SW.zip and AN223SW.zip. If you are using a 5.x driver and need support you can download Legacy OS Software.
I want to switch to conservative or powersave CPU scaling governor to lower temperature. However, I can only find 3 available governors: ondemand, schedutil & performances. As far as I know, the acpi-cpufreq scaling driver should have other governors such as powersave, conservative or userspace. These governors also existed in my previous Debian installation.
I've followed the steps here, and also taken into consideration the limitations for the docker driver (reported here), that have to do with runtime security options. And when I try to start minikube the error I get is : Failed to start host: creating host: create: creating: prepare kic ssh: copying pub key.
I suspect that the error has to do with the security settings issues with the docker driver, but this seems to be like a dog chasing its tail: if I don't use rootless mode in docker and I attempt to start minikube with sudo (so that docker can also start up with a privileged user), then I get this:
It happens sometimes also when different driver is used and it is run as a VM and basically deleting such VM may help. Usually running minikube delete && minikube start is enough.
In this case, when --driver=docker is used, your Minikube instance is configured as a container in your docker runtime but apart from container itself other things like networking or storage are configured.
I guess it could be simply clearing some cached data that helped in your case and removing broken references to non-existing files. The above message explains quite clearly what couldn't be done, namely docker couldn't copy a public ssh key to the destination minikube:/home/docker/.ssh/authorized_keys as the source file /tmp/tmpf-memory-asset544814591, it attempted to copy it from, simply didn't exist. So it's actually very simple to say what happend but to be able to tell why it happened might require diving a bit deeper in both Docker and Minikube internals and analyze step by step how Minikube instance is provisioned when using --driver=docker.
