I have unRAID 6 beta 10 and I have a Windows 8 virtual machine running.  I am already doing USB passthrough for my LaserJet 1012 and it all works beautifully.  My issue is my FTDI USB-to-Serial passthrough is not working.  After I set it up, my host machine does not see this USB device at all, so I can't install drivers for it.  I even tried serial = '/dev/ttyUSB0' with no-go.  This is an HVM.

 

Anybody can shed any light?  Thanks!!!

I am confused?    If you are doing pass-thru then I would expect the USB to be handled via the VM and not the host.

Hi

 

How are you doing passthrough, via discrete USB passthrough or PCI passthrough of the USB controller?

 

Can you share your VM config file as well as the output of LSUSB and LSPCI?

 

Thanks

You never need to install drivers on your host.  Only the guest.  Are you passing through the USB devices individually or the entire USB controller?

 

Edit:  just saw meep beat me to the same question...

 

I found out my problem.  My specific USB-to-Serial is not Windows 8 compatible  :-O    I feel like a dumbass...  LOL

 

It worked on a Windows 7 VM.  So time to get a new adapter!  I was using individual USB, not the controller passthrough.

Problem is still not solved.  Tired 4 different USB-to-Serial adapters and my host machine does not see any of them.  I need a Win8 VM...

 

Tried:

 

1. PL2303

2. FTDI232R

3. PalmConnect (first one that didn't work)

 

Does anybody know of a good one to use?  The first 2 work on unRAID, I see a /dev/ttyUSB0 but how can I passthrough a serial connection?

 

Thanks!

Forgot to add my .cfg file:

 

builder = 'hvm'
vcpus = '4'
memory = '2010'
device_model_version="qemu-xen-traditional"
disk = [
        'file:/mnt/cache/custom/Windows8.img,hda,w',
#        'phy:/dev/vg1/winDATA,hdb,w',
#        'file:/mnt/user0/Data/Install/Operating Systems/Windows/Win8_x64/Win8Pro-x64-en-US_Jan2013.iso,hdc:cdrom,r'
]
name = 'Windows8'
vif = [ 'mac=00:16:3e:31:d5:4b,bridge=br0,model=e1000' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
boot = 'dc'
acpi = '1'
apic = '1'
viridian = '1'
xen_platform_pci='1'
sdl = '0'
vnc = '1'
vnclisten = '192.168.25.2'
vncdisplay = '1'
vncpasswd = 'xxxxxxxx'
stdvga = '0'
usb = '1'
usbdevice = ['tablet','host:067b:2303','host:03f0:0d17']
#pci = ['01:00.0','01:00.1','00:1d.0']

 

I even tried adding the "usbdevice" on their own lines, no change...

 

Here is my "lsusb" from my unRAID box:

Bump - Nobody knows of any Windows 8 compatible USB-to-serial adapters I can use under XEN/Windows 8 VM?

No clue about the XEN part, but the tripplite keyspan is kind of the gold standard for compatibility. If that model doesn't work, I'd be surprised.

Thank you!  Ordering one, will report back once I get it.
