We want to use a "Reiner SCT" Cardreader inside a KVM based VM for online banking with Hibiscus. The card reader is connected directly to the proxmox host.

Code:

We assigned the Card Reader to the VM with this command:

Code: 
qm set 104 -usb0 host=0c4b:0400

Information from inside the VM (based on Ubuntu Linux):

Code: 
uname -a
Linux hibiscus 2.6.24-26-server #1 SMP Tue Dec 1 19:19:20 UTC 2009 i686 GNU/Linux

cat /etc/debian_version

As soon as the VM tries to access the cardreader, it crashes immediately - unfortunatly, I have no information in the log about this error. Is there another possibility to debug this?

maybe can you test qemu-kvm from proxmox pvetest repository ?
A lot of usb patchs have been applied since last version.

Unfortunatly, this is our productive system. I just updated on Friday from Proxmox 1.8 to 2.1 (by exporting the existing VM's into backup archives, made a clean installation and re-imported them). USB passthrough was not functional with 1.8 either, we had to use a special software to redirect USB access over the network from the proxmox host to the specific VM. I thought that we can avoid this with version 2.1.

I can test the new pve repository next weekend with the specific VM - is there already a specific date on which the next version will be released?
