e200 "USB device not recognized"
« on: March 17, 2007, 12:26:12 PM »
"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."

I just installed rockbox on my sansa e270 successfully.  When I try to add songs or what not (In my case a theme) it does not show up in My Computer and it errors on my computer.  The screen on the Sansa shows that it has a USB connection however.  Any suggestions?

Are you in Rockbox? Rockbow will show a USB icon because it can detect the USB cable plugged in, but has no USB support.

You need to be in the original firmware.

Is this way of operation temporary and will change eventually?

I like the way I can connect the iRiver h-140 with rockbox to the computer and I wish to see the same feature when using the sansa. My cousin bought the sansa e260 and I installed rockbox as soon as I got it in my hands. He really likes it.

For rockbox to support USB on the sansa, ipods and a few other players a full blown USB stack has to be implemented in software, this is a lot of work and will take a long time to do if it ever gets done. On iriver h100/h300, gigabeat old archoses, iaudio x5/m5 the usb is handeled by a hardware chip and rockbox just detects the connection and hands over control to the chip.

Got it!

Rockbox is great even with that minor "issue".

Just finished downloading a bunch of WPS to try them out in the DAP.

Thanks for clarifying how the USB works.

Now it makes sense, I was wondering why the USB code for the gigabeat is less than 10 lines. :D

iRiver H10 5GB, Gigabeat F40, Gigabeat S60, all rockboxed. :P
