Hello,
I have usb smartcard reader connected to my machine. When running
dispcal the card reader stops working. Restarting the software which
is using the card reader (VDR with softcam) gets the reader working
again.
This has something to do with dispcal enumerating usb devices. Even
running just dispcal --help has this same effect.
Card reader is using usb-serial-driver. What could cause this
behavior? Is there something that could be done with Argyll or is this
problem with the usb-serial-driver?
I'm using dispcalGUI and running that has the same effect. This isn't
a huge problem. I don't run dispcal or dispcalGUI that often but it's
quite annoying when you don't remember this and accidentally leave
the card reader in non-working state.
I'm using Debian Wheezy 64 bit and tested this with Argyll 1.3.5.
Here's some information about the card reader:
