the linux kernel did create a file /dev/ttyACM0, but any access will lock system for several seconds(permission is correct). And then check the kernel log, you'll find some usb low-level timeout event.
So I think the main firmware on AVR32 has some bug, let the usb device not a standard one.
Try opening the port with a standard serial terminal program such as PuTTY - that should set the baud rate (while directly cat'ing to /dev/ttyACM0 won't). The device firmware may time out unless the port settings are indicated beforehand.

Studio 4, or Studio 5? If the former, I've been using Tom's programmer loaded with my code for quite a while under Studio 4, with no issues at all.

TopI guess this is the best place to post the issue, other than support group for LUFA.
I have an issue with Xplain Bridge on windows 7 32 Bit(Enterprise).
when i try to load driver file(.inf) it just doesnt works.
i made Xplain work as MKII so i think is not really my hardware.
anyone have any suggestions to solve this?

TopAre you using the .INF file located on my website? If so, are you running in Serial Bridge mode, or AVRISP-MKII mode?
If the former, give Windows the INF from my site. If the latter, you need to give Windows the location of the Atmel AVRISP-MKII drivers, which ship along with AVRStudio.

Topdoes LUFA work for new Xplained board(shiped with at32uc3b1256) now?

TopThe LUFA core is ported, but that project is not. I've been busy with a few other things lately, but given the large amount of interest perhaps I should re-prioritize.
The big changes would be writing an appropriate UART and SPI driver for the AVR32s, and fixing up the endianness issues in the demo.

Topnice guy!!
i'm new to avr32, in my xplainED board, i can switch AVR32 into bootloader mode via the jumper. And I can use dfu-programmer access the AVR32 chip, so I think I can re-program it. The question is, if I upload a hello world program into, will the DFU bootloader(on AVR32) be broken?
If the operation is safe, I also want join your LUFA proj to let xplained broad works well under Linux.

TopThe serial bootloader in the XPLAINED boards is why I haven't put in the effort before now to port the bridge firmware in LUFA; you can already do both debugging and programming through the existing board controller.
Yes, you can reprogram the AVR32 through the bootloader without damaging the bootloader; that's the point. Reprogramming with an external programmer such as a Dragon or JTAG will erase the bootloader however.

No, i can't do it under LinuX, even i can't import the device into my virtualbox(which m$ windows there)

if re-programming AVR32 via bootloader is safe, i'll try some testing code
Thank you!
