Hi Greg, I am currently testing my device(eZ430) using generic usb-serial driver, and I came across some strange problem. If I test the device with x86, it works very well. It sends character strings to USB serial, after pressing key on device. But when I test with ARM board(Beagle), it shows some characters missed in between.(for ex "Hello" receives as "Helo" with "l" missed) While debugging, I enabled debug messages with debug=1 while modprobe. And I started getting data properly with no characters missed. I found out that it was "usb_serial_debug_data" function from "usb_serial_generic_read_bulk_callback" printing data received.ow But here, If I disables debug, I starts getting data corrupted again. in short "modprobe usbserial debug=1" works very well but "modprobe usbserial" doesn't. Is there any possibility that specific to my device, it needs the urb flushing to be delayed some time using debug messages? What could be the probable reason? How can I debug these problems? Thanks for your help.
