#3 lore raw

I noticed the bug is triggered when the GTM382 module is connected on my PC/104+ board through the PCI Express MiniCard.
Using Option deviceKit plugged on the CPU board through USB 1.1 connector, the bug isn't triggered.

#4 lore raw

Is still possible to send AT commands and get any network traffic through once this problem occurred, or is there no communication at all possible with the module ?

Can you try again with debug enabled (module parameter debug=0x1F) ?

Since it works on USB 1.1 but not on USB 2.0, my first guess would be that there's something wrong with the host controller or the host controller driver.

no it's not possible to send other AT command.
Minicom fails to connect on any ttyHSx port.

I should also mention I'm using a Transmeta Crusoe CPU board.
