Hello,
I'm testing an embedded system, which is running a somewhat dated
(May 2009) 2.6.28.10 kernel.
When I plug this cheap 2-GB USB drive, I get the following message:
hub_port_init 1
Plug in USB Port3
udev->speed: 3
usb 3-1: configuration #1 chosen from 1 choice
usb-storage: This device (058f,6387,0104 S 06 P 50) has unneeded SubClass and Protocol entries in unusual_devs.h (kernel 2.6.28.10)
Please send a copy of this message to <linux-usb@xxxxxxxxxxxxxxx> and <usb-storage@xxxxxxxxxxxxxxxxxxxxxxxx>

And, when I try to list the drive's contents, I can't:
(while WinXP "sees" the contents)
# ls -l /dev/sda /dev/sda/ /dev/sda1 /dev/sda1/
ls: /dev/sda/: Not a directory
ls: /dev/sda1: No such file or directory
ls: /dev/sda1/: No such file or directory
brw-rw---- 1 root 0 8, 0 Jan 1 00:06 /dev/sda
Given the age of my kernel, there is a good chance this problem
has been already been fixed in recent kernels. Is it the case?
For reference, here's my boot message:
