Dk1633 Drivers

[Annette Fazzari]

Irealise this is a very old thread, but I'm considering getting a new MBP 13 and have a trusty Lenovo USB3 dock which I'd prefer not to have to replace (it's not necessarily a deal breaker but could be another $150-$250 I'd prefer not to spend in switching back to Mac).

I'm using that dock on MBP for additional screen + printer. Aukey made a great USB-C power pass-thru adapter that includes USB 3.0 ports and HDMI port as well. i got it on amazon for something like $45.

While Lenovo doesn't supply a driver for the display adapters, the chipset inside it (and as far as I can tell, all other USB 3.0 to DisplayPort devices) is provided by DisplayLink. You can install the generic DisplayLink adapter drivers directly from their website at:

I am using the Lenovo usb 3.0 dual monitor docking station with the new beta drivers March 13 2015. I think they got it right now. No more screen blinking when watching videos and ethernet is working great. I have Mac Book Pro 15.4 11.2 Mid 2014. This is my first mac.

Yes in that the MacBook Pro (as opposed to the MacBook) can support more than 1 external monitor. However, as you've already discovered, if you connect them separately, it works. Unfortunately, you can't daisy chain monitors from a single port; you must use separate ones. Use of the dock still doesn't increase the available video bandwidth of the Thunderbolt/DisplayPort port even if the machine itself has the capability.

The ThinkPad Docks use the DisplayPort Multi Stream Transport (MST) Hub standard on the two exposed DisplayPort ports. This technique allows multiple external monitors to act as extended screen area as long as the hardware and driver support MST Hub. Without MST Hub support, multiple external monitors on the dock can only act as mirrors of each other. Unfortunately, macOS does not support DisplayPort MST Hub. Only Thunderbolt chained monitors are supported. Presumably, Apple regards MST Hub as a legacy, dead-end technology.

Currently (April 2021), each Mac Thunderbolt 3 port supports only one display per Thunderbolt 3 port, and it needs to be the last one in the Thunderbolt 3 chain. I don't know for sure, but I suspect this refers to monitors using the DisplayPort Alternate Mode on the Thunderbolt 3 chain.

The Lenovo Thinkpad dock will support 2 separate displays. I found that if I plug one into the back of the dock (displayport to displayport) and the other into the front of the dock (displayport to USB-C) it'll run them both as separate displays along with my MB Pro 16 display.

I currently run 4 displays off a single USB-C port to a thunderbolt dock. I have 2 of the lenovo docks daisy chained and I only plug 1 USB-C cable into my laptop. If you are having an issue with it duplicating your display check your drivers and the setting on the dock.

This was working for me (15" MacBook Pro, 2018) with 2 Dell monitors connected using a ThinkPad Hybrid USB-C with USB-A Dock, with a single USB-C cable providing my laptop with power and driving the two external monitors as separate displays (not mirrored). Unfortunately that dock went back to work, and I bought a ThinkPad USB-C Dock Gen2, which looked similar. Using this dock, the external displays are mirrored. I have the DisplayPort software installed and I have tried everything I could think of. So I'm going to try and negotiate a return / replacement.

go to page 18, you'll see the USB C dock gen2 does not rely on displaylink tech. Which means it cannot be supported to display the second extended screen (3rd screen) without using a USB-C to HDMI (hopefully with displaylink) enabled.

i checked there's no new firmware update, and i went to view system settings on mac, indeed i couldn't find any traces of displaylink. I also installed displaylink manager 1.8.0 and 1.8.1 and it stated that it couldn't find any displaylink related device (no displaylink enabled display).

I solved this puzzle by connecting one of the monitors straight to the Macbook using a USB-C/HDMI cable. All the other stuff is connected to the docking still. One of my monitors has 3 ports, so, I pretty much have 2 cables connected to the same monitor. One running to the docking and the other to the Macbook. When I connect the docking station to my Dell/Windows laptop, it recognises both of the monitors from the docking, while the MacBook, ignores one of the connections and recognises the HDMI connected to the USB-C.

Get the OWC Dual Display port adapter. It's Thunderbolt to Dual DisplayPort. ( -dual-displayport-adapter). make sure you have real thunderbolt cable, this was the hardest part, I went through several 'cables' from Amazon that were not really thunderbolt 4. I ended up buying an OWC branded one.

After that, both monitors work. There must be some chip extensions in there. I can use the two displays, and the onboard LCD just fine this way. It's not using the onboard DVI ports of the dock, and its a dongle, but it makes it all work.

"I have a 64GB USB flash drive that I haven't used for about a year. Now I constantly get a massage saying that the device has malfunctioned. Device Manager shows a similar massage. I formatted the USB drive twice now and still get the error. I tried unplugging and plugging the device, but nothing changes. I cannot find any further information about the USB drive in Device Manager except the hardware ID is USB\DEVICE_DESCRIPTOR_FAILURE. What should I do to be able to access the USB device properly?"

Your USB device cannot be recognized or reports device descriptor request failure error in Windows 11/10/8/7? We use USB devices all the time and it is quite frustrating when it is malfunctioned, not working or not recognized in Windows.

What does "Unknown USB Device (Device Descriptor Request Failed)" error mean? The USB device descriptor is used to store information for USB drives and it is responsible for recognizing different USB devices. If it fails to work properly on Windows 10 or Windows 11, the USB drive cannot be recognized by operating system and you may get errors like code 43. When you insert the USB device to your computer, you may get one of the following messages depending on your PC.

If you open Device Manager, you can see the USB device which is displayed under Universal Serial Bus controllers is marked with a yellow exclamation icon and with message "Unknown USB Device (Device Descriptor Request Failed)". If you check its properties, you can see error message " Windows has stopped this device because it has reported problems. (Code 43) . A request for the USB device descriptor failed" in the Device status section of the General tab.

In addition to error messages above, you may also encounter other symptoms, for example, the USB device my repeatedly disconnect and reconnect automatically, making it difficult to use. In some cases, the USB device might become unresponsive or not respond to any commands from the computer. Sometimes, the Device Descriptor Request Failed error is not limited to USB storage devices, which means it may also occur to other USB peripherals such as keyboards, mice, printers, etc.

Bad sectors are areas that cannot be read or written, if a disk contains too many bad sectors, you'll have to consider replacing it with a new one. Here we'd like to recommend free partition manager software to check and repair bad sectors for USB drives. You can download DiskGenius Free Edition and follow steps below to repair damaged USB drives. It should be noted that the bad sector scanning process is safe, and yet the bad sector repairing process damages data and you should back up or recover data first if you want to repair bad sectors on USB drives.

The fast startup feature relates to hibernate and shutdown, which is designed to make computer boot faster. However, some users report that this feature makes computer performs so quickly that Windows 10 cannot detect USB device and the USB device descriptor failure appears. If that is the case, you can follow these steps to turn off fast startup.

In some cases, operating system will put the USB port in low-power mode if the USB selective suspend setting is enabled. If so, the USB drive connecting to this port won't be able to work normally and cause USB device_descriptor_failure problem. To solve the problem we can try disabling this feature via following steps:

Windows updates are crucial for keeping your operating system secure, stable, and up to date with the latest features and improvements.
