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: http://sourceforge.net/mailarchive/message.php?msg_id=3737890 ...was much more in-depth, but I'll add: /var/log/messages output: Mar 29 11:13:03 localhost kernel: hub.c: USB new device connect on bus1/2, assigned device number 5 Mar 29 11:13:03 localhost kernel: usb.c: USB device 5 (vend/prod 0x8341/0x2000) is not claimed by any active driver.
