Topic: iriver H140: USB problem =>unknown device

[Arni99]

suddenly i can´t access the 40Gb harddisk anymore.
my USB-notebook port and the cable are ok....tested another external harddisk at the same port and with the same cable.

is there some hardware-USB-controller inside the iriver which might have died?

recording works flawlessly but i just can´t get the stuff from my harddisk to my notebook via USB?!

thx

deleted all files, did a format via the original iriver firmware and it worked

Ouch!

Sorry to hear that. The USB connection is handled through one chip that connects the disk to both processor and USB bus, and the processor switches it between both. So if it's not accessible through USB, it doesn't look good.

What device did you have again? h140 or h340?

For h1x0: the usb is on a daugtherboard, maybe a broken soldering?
For h3x0: if I ever get USBOTG working in rockbox, there's a small chance I can make it work in device mode so the disk is accessed in software over the second port (but at a much slower speed). So don't toss it away....

It´s a black H140 as you can see in the subject of this thread.
Thx for your kind words petur, I will disassemble it and check if I can find some broken soldering.

LMK if you want to sell this if you can't fix it
