Hi,

I have an Xprotolab Plain that I cannot get to show up through USB.  (I have tried both Ubuntu and Android, and both claim there is no USB device connected.)

The list of attached devices from lsusb does not change when I plug in the device; it simply doesn't show up.  I believe that there is a red LED that is supposed to flash with USB activity, but I have never seen it.  (The green LED stays lit continuously.)  I've tried shorting pins 1 and 6 of J8 to activate the bootloader before powering, but still no USB device.

I've had the board for quite a while, and have tried several times to figure out what's wrong, but now need to use it and need help getting it connected.

Thanks!  -David

P.S. The packaging shows HW: 1.0, if that makes a difference.  Obviously, I can't see the firmware version.

Hi, can you try with a different USB cable? If it doesn't work, perhaps you will need a replacement. Send me an email.

Hi, Gabriel,

Thanks for the reply.  Much to my amazement, I tried a different USB cable and it worked!  (I thought I had tried more than one when moving from my laptop to my Android tablet, without any success, but now both work.)  So I guess this was user error!
