hi,
we are using spicy to share the USB devices between thin client and VM in
Server.
however, it shows that
- the menu of spicy can show more than 5 detected USB devices
- if enable more than 5 USB devices, spicy will prompt the error of out of
number of supported USB devices.
I am not sure is there implement limitation in spicy source code ? or this
issue can be avoided by changing build configuration ?
The limitation comes from the number of usb-channels / usb-redir devices
configured on the
qemu cmdline / inside libvirt
The ehci controller has 6 ports, so if you remove any virtual usb-devices such
as a usb-tablet,
you can configure one more channel. For more channels you need to add a second
ehci controller
+ companions. Alternatively you could configure the ehci controller to have
more ports,
but I think that requires qemu source-code changes atm.

Hans
