Usb keys (again) with same vendor and id

Hi,

in a windows VM I was able to push a usb key using this: qm set 100 -usb0 host=6666:7b3c

Now, I have a second usb key of the same type, so with the same id and vendor.

Here is my lsusb
Code: 
root@proxmox:~# lsusb
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 005: ID 6666:7b3c Prototype product Vendor ID
Bus 004 Device 004: ID 6666:7b3c Prototype product Vendor ID

How can I push it in a second windows VM ? I searched the forum and found something about using bus and device id but it was using usbhost parameter which I asume it was for different versions of qm.

Further, I tried to push the same key into 2 different VM but of course it is exclusive. Is there a way to share just one usb key in two vm without clash ?



Thank you
 
Thank you for your reply. Please, I need a bit of help. I'm trying but I'm missing something, of course. This is lssub output:

Code: 
Bus 004 Device 005: ID 6666:7b3c Prototype product Vendor ID
Bus 004 Device 004: ID 6666:7b3c Prototype product Vendor ID

I was able to inject the first usbkey with host=6666:7b3c.

Now, on the server I have a second similar usb key, I think the second one in the list above. Here is lsusb -t output:

Code: 
/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/4p, 12M
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/5p, 12M
/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/5p, 12M
    |__ Port 2: Dev 5, If 0, Class=HID, Driver=usbhid, 1.5M
    |__ Port 3: Dev 4, If 0, Class=HID, Driver=usbfs, 1.5M
    |__ Port 5: Dev 2, If 0, Class=HID, Driver=usbhid, 1.5M
    |__ Port 5: Dev 2, If 1, Class=HID, Driver=usbhid, 1.5M
/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/4p, 480M
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/5p, 480M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/5p, 480M

I tried to inject into VM 102 with this command, after many attempts with parsing errors because I did not understand the syntax:

Code: 
qm set 102 -us0 host=4-3.4

This one is ok but I cannot see into VM the usb key :O. I tried also 4-5.2 but nothing to do :(

What am I missing ?

Thank you
 
Ok, I used dmesg output when I disconnected and attached again the usb key. So, when I disconnected I had:
Code: 
usb 4-2: USB disconnect, address 5

so I think is it host=4-2.5, that's right ?

Following dmesg output when I attached the key again:
Code: 
usb 4-2: new low speed USB device using ohci_hcd and address 6
usb 4-2: New USB device found, idVendor=6666, idProduct=7b3c
usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 4-2: Product: ExseKey USB
usb 4-2: Manufacturer: Clover Informatica
usb 4-2: SerialNumber: ã¨
usb 4-2: configuration #1 chosen from 1 choice
generic-usb 0003:6666:7B3C.009F: hiddev96,hidraw2: USB HID v1.00 Device [Clover Informatica ExseKey USB] on usb-0000:00:12.0-2/input0

... and it seems it started using addr 6.

Now, I injected host=4-2.5 and then 4-2.6 but nothing to do, the key was not read by my software :(. Of course, I stopped the VM and started it again for every qm set.

Any idea ?

Thank you very much.

What info do you get in the qemu monitor ('info usbhost')?

I got this:

Code:

Yes, I need two similar keys for two vm different istances. Try to share just one key for both vm but with a clash.

Again it is added 2 time to one VM - I thought you do not want that? To clarify, please post the vm config - together with the 'info usbhost' output.

Ok, well one key have to go into first vm id=100 (and it is because I used vendor_ID). The second key have to go on the second vm id=102. Here is the output:

102.conf
Code: 
cat /etc/pve/nodes/proxmox/qemu-server/102.conf
bootdisk: ide0
cores: 1
ide0: local:102/vm-102-disk-1.raw
ide2: local:iso/windows7.iso,media=cdrom
memory: 768

net0: rtl8139=5A:2D:99:37:B1:40,bridge=vmbr0
ostype: win7
sockets: 1
usb0: host=4-2.6

Here is qm monitor info usbhost. You are right, here it seems added 2 times. But in config file there is just one row :O.

Code: 
qm monitor 102
Entering Qemu Monitor for VM 102 - type 'help' for help
qm> info usbhost
  Bus 4, Addr 2, Port 5, Speed 1.5 Mb/s

Thank you

Oh, you use PVE2.0 RC1?? You posted in the wrong forum!

arghh sorry :(. Anyway, I stopped many times VM ... but I'm confused now. In conf file there just one key injected, while in qm monitor there are two. Maybe I can try to erase the row in 102.conf file and let qm monitoring output as it is ?

Thank you.

Please can you test with '4-1.5' instead?

Ok, I started again from scratch. I removed from first and working VM 100 usb injection.

Now I will have VM 100 Windows XP and 107 Windows 7.

4-1.5 does not work :( and the key is not seen now on vm 100.

Here is my complete lsusb -t output. Now attached on the server I have just 1 usb key. The other one is off.

Code: 
lsusb -t/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/4p, 12M
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/5p, 12M

Thank you
 
OK, seems the forum formats the output of 'lsbusb -t' in a wrong way. Please can you try to post it correctly formated - or provide a screenshot instead?
