USB Troubles

[Paul Jones]

Hi All,

I've been having troubles connecting via USB (in Windows 8.x). Most of the time when I connect the usb cable I get a serial port that doesn't work, and no mass storage. Occasionally the serial port will respond and mass storage works. This was driving me nuts so I tried to use it in Linux, where I discovered that it wasn't actually a windows problem (for a change!!). It was doing the same thing but now I can see what is happening.

Originally I was using my desktop computer, then changed to a mac book pro. Both do the same thing.

This is the dmesg output when I pulg it in and unplug it from both usb ports. Any ideas? I use the LPC1768 on one of my designs so I can quickly replace it if needed.

Thanks,

Paul.

Have you tried with different USB cables? I've seen similar log messages when the cable was bad. Also try connecting directly to the computer of you are using a hub.

Also try powering smoothie from an external source, if you power from USB and the USB has problems with the power it will reset

Are you using one of the TL beta boards?

They have a fault which causes log messages similar to the ones you show- the USB_CONNECT signal is shorted to ground by some bridges between the ground plane and a via.

See http://triffid-hunter.no-ip.info/101_0138_highlighted.png

The fix is to scrape those bridges away using a sharp tool (and magnification if you need it)

The reason this fault causes the described behaviour is that it causes the host computer to think that smoothie is ready to talk USB when it's actually not ready at all.

Another possibility is a bad uSD card, or a poor quality USB cable.

The uSD provided with the recent kickstarter batch is (unfortunately) a dreadfully poor quality chinese clone, fit only for the rubbish bin.

A genuine uSD from a reputable supplier will make a huge difference if that's the issue.

If you're curious, class 2 is probably best- higher speed classes sacrifice random performance for sequential performance, but filesystems mostly do random access.

As for the USB cable, you should use a short-ish cable with one or two ferrite beads, plugged directly into your computer (not via a hub).

Bingo! This was the problem. After fixing the via it works correctly.

Thanks,

Paul.

Thanks for letting us what solved it for you, and welcome to the smoothie community!
