its probably the Intel driver issue. Will unistall and use the windows driver instead - that will fix it as am reading other forums as well.

In Windows (Davicom USB) network adapter is removable devices! There is a problem.
Just testing Lubuntu 14.04.2 (32-bit, kernel 3.16.0-31) that I have installed 16GB USB flashdisk. I have compiling drivers LAN + WiFi and introduced modules dm9620.ko + r8723bs.ko. The network works and having installed VLC, everythings O.K.

I still don't know why it sometimes looses it's VID

PS. I don't have the problem so I won't try it...
You can test it.Last edited by oversx; 03-17-2015, 17:32.

1. Use the shipped power supply. Or at least measure with a multimeter that your power supply has a uniform voltage over time.
2. Buy an external USB to ethernet adapter.

The VID&PID will be stored in the Davicom chip (about the eeprom) or in BIOS?
I have power supply of notebook 12V/5A.

Originally posted by vprasinos View PostDoes it disconnect while playing a game/movie?? Ok my unit has never done this. Only some times after boot finishes it fails to detect the adapter. A reboot fixes that.
An edit to DM9USB.inf I think will not fix that. It needs more sections to edit in the file. Also the VID going to 0000 seems like the pipo looses the usb connection to the ethernet adapter (due to power?). Maybe another power supply might fix it...

another fine example of how the Chinese want to screw us. I wonder if they do this stuff on purpose?
