USB does not "attach"


Hello,

I have bought an e-book reader (H-MC Ebook Reader 6" E-ink 2GB code:HMC-601) and when I tried to attach it to my ubuntu (Ubuntu 9.10) and the first time I attached the e-book reader I could successfully connect (got a window with all files etc...) but when I tried to transfer files to the e-book reader he just "snapped" out and closed down the connection.

I thought, just a small error, I will just try it again but now nothing happens.

I used the command dmesg to see what happened to the connection and this showed up:

Code:
[  347.166146] usb 1-1.5: new high speed USB device using ehci_hcd and address 9
[  347.255956] usb 1-1.5: device descriptor read/64, error -71

When I tried it on another USB port I got the message

The command lsusb reported

Code:
Bus 002 Device 004: ID 04f2:0420 Chicony Electronics Co., Ltd 
Bus 002 Device 003: ID 1532:0016 Razer USA, Ltd 
Bus 002 Device 002: ID 8087:0020  
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0020  
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
(Chicony Electronics Co., LTD is my wireless keyboard and Razer USA is my mouse.)

Anyone got an idea why it worked first and then it said something like "I hate you, I won't work anymore".

I contacted their support base because their ebook reader doesn't work either on Windows (just "unknown error with USB") but no response yet from them.

Their are no drivers for this e-book reader (didn't find anything on their website).

Can you help me?

If it doesn't work with linux or win then it is broken.
Send it back.

Just a wild guess, but it might well be overcurrent in the port. Transfers, start, something (linux or the e-book) hits an overcurrent and switches off the port. Hence the changing device number

Is _the_ebook's_ cable being used? it might be differently wired.
