Good morning.
I have a usb key for digital signature and site authentication that, teorically, should be perfectly supported by usb_modeswitch (TargetVendor=0x072f; TargetProduct=0x100d).
It should switch the key to: TargetVendor=0x072f; TargetProduct=0x90cc.

Usb_modeswitch is preinstalled in Antergos KDE, but without the corresponding “data” pack, that I can’t find in AUR.

But, as far, it did work just one time, and that one time the usb key was working great.
That sigle time I was removing then reinstalling all the package to make it work (pcsc-perl, pcsc-tools, ccid, pcscd, ibminilector38u-bit4id, opensc-opendnie-git).

My “extract” lsusb now - key not working - is:
Bus 002 Device 004: ID 072f:100d Advanced Card Systems, Ltd

The day it was flawlessly working I had the right switched lsusb:
Bus 001 Device 005: ID 072f:90cc Advanced Card Systems, Ltd ACR38 SmartCard Reader

I have another partition - I was ready to delete - with Linux Mint, and there usb_modeswitch works great.

Anyone familiar with such issue? I understand it should not be common.
A help would be truly appreciated.
