arduino USB serial device breaks on lucid kernel upgrade
Filing bug report on behalf of someone else.
With Lucid kernel 2.6.32-24.43, the device and attached program work correctly.
Upon upgrading to 2.6.32-25.45, the program stops working.
The device is:
Bus 001 Device 005: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
A quick driveby browse of recent commits in that time window suggests this might be related, but this is merely a guess based on inspection. No bisection was done.
lspci, lsusb, and test code to follow.
