If you suspect this might be related to the problem, you can try to disable the auto-suspend of your FT4232 device. http://www.mjmwired.net/kernel/Documentation/usb/power-management.txt > I'm using linux 3.1.0, libftdi 0.19 and libusb 0.1.12. What if you move to libftdi-1.0 and libusb-1.0? -- Xiaofan -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
