Debug  lsusb -v

The following information for analysis of the problems we are having with the
OpenSuse :

42.2 64 bits Kernel 4.4.74-18-20-Default kernel x86_64
42.3 64-bits Kernel 4.4.75-1-Default x86_64

Our difficulty is to connect the Gertec ppc 900 / 910/920 brush to the USB
ports, where some hardware uses the uhci and other ehci modules.

It is compatible with / dev / ttyACM0 ID 1753

Gertec Device


Only works with the computer off

This error affects the 32-bit and 64-bit versions of openSUSE (42.2 and 42.3),
but does not affect SLE.

The required kernel module is cdc_acm
Gertec pinpad is not working on openSUSE, even with kernel-vanilla, but it
works on Linux distributions like Fedora, Redhat, Centos, Debian, Ubuntu ...
and Opensuse Kernel 3.12-64 - 67


Follows result of the lsusb -v command
Here's the dynamic debugging done with

Echo "module cdc_acm + mpf"> / sys / kernel / debug / dynamic_debug / control
