There have been two posts recently to linux-usb-users regarding problems that I'm also experiencing. Perhaps someone on the developers list would like to pick this up and run with it.
Here are key parts of the recent messages, I can provide copies of the full messages for those interested. There's definitely something going on. I'm having trouble with the 2.5.25 kernel on my MIPS hardware, since the include/asm-mips directory is incomplete. I'm more than willing to test updated USB drivers for the 2.4 tree though.

I turned on verbose debugging, and my 'mkfs -t ext2 /dev/sda1' resulted in the following: (lots of successfull xfer 4096 bytes; xferred 4096/4096; transfer complete) usb-storage: usb_stor_bulk_msg() returned 0 xferred 4096/4096 usb-storage: usb_stor_transfer_partial(): transfer complete usb-storage: usb_stor_transfer_partial(): xfer 4096 bytes usb-storage: command_abort() called hcd/ehci-hcd.c: 00:13.2 urb_dequeue 8151be60 qh state 1 hcd.c: giveback urb 8151be60 status -131 len 0 usb-storage: usb_stor_bulk_msg() returned -131 xferred 0/4096 usb-storage: usb_stor_transfer_partial(): unknown error usb-storage: Bulk data transfer result 0x2 usb-storage: Attempting to get CSW... At which point it was stuck until I disconnected the USB cable. -- Tom Collins [EMAIL PROTECTED] ------------------------------------------------------- This sf.net email is sponsored by: Jabber - The world's fastest growing real-time communications platform!
