Hi,
I'm trying to get the Ego Technology MD100 to work under linux. It's
small MP3 player gadget which has 128MB of flash and a USB interface. It
identifies itself as a USB storage device. When I try to read from it
under linux, the process doing the read just hangs. The device works
under windows 2000 with the default windows USB storage driver.
I'm running the stock 2.4.20 linux kernel.
attached is the dmesg output, the output of /proc/bus/usb/devices and
.config of the kernel.

Peter,
Did you ever get an answer? Were you able to get this working?
I have the same device, although it's marketed differently (claiming
Linux 2.4.x compatibility!) as a PowerColor MD100 128MB Portable
Storage/Music DISK USB MP3 Player:
http://www.ateck.com/viewItem.asp?idProduct=453055232
From the vendor power-color.com:
http://www.power-color.com/html/md100.html
But, it has the same USB device/product ID's as yours (0x8341/0x2000).
Furthermore, I have the exact same problem. I've tried it on 5
different Linux Boxes, ranging from SuSE 7.3 to 8.1 and RedHat 7.2 to
7.3. The kernels range from 2.4.9 to 2.4.20; all have USB properly
installed and working for other devices, including other pen drives.
The SuSE based machines hang tight (need to power cycle) about a minute
after installation of the device. On the RedHat machines, they see the
device, but any attempt to read the device (i.e. fdisk -l, dd
if=/dev/sda of=/dev/null, mount /dev/sda ...) locks up the process
and either the usb-storage or the sd_mod driver (I don't know which).
Peter's information, at:

...was much more in-depth, but I'll add:
