I've seen similar when running on a virtual machine on the mac... To get around this I installed Ubuntu on an external USB drive and can run either natively from boot or under a virtual machine under windows and it works fine.
If you are running natively it could be the hardware but I imagine that was all tested before it was sent out.

Hey,
We just got a Tiny 2.11 board (from PPZUAV), and are having some issues
right off the bat. It appears that my computer (and several others I've
tried) isn't recognizing the USB programming cable. When we try to
upload a configuration to the Tiny 2.11, the Paparazzi center program
outputs "no USB device." It seems like the USB port just isn't being
recognized; dmesg gives the following output after turning on the Tiny
with the USB cable connected:
[ 8504.168149] usb 3-1: new full speed USB device using uhci_hcd and

Has anyone seen this or something similar?
Thanks!
