Identical USB devices - the "rare and convoluted technique"
Posted: 9. Jan 2019, 22:57
So I'm now in the same boat as some others: I have two USB security dongles showing completely identical information in the USB filter. One key needs to stay in the host PC (Windows 10) and the other has to go into the guest (Windows 7). It needs to be automatic, since I'm using the VBoxVMservice add-on. As expected, Virtualbox can't tell them apart and both go into the guest. (I'm running version 5.2.20 with matching Extension Pack)
I followed Socratis' USB basics and troubleshooting tutorial and get the USB keys both appearing in the guest. At least that works, but not quite what I want.
I used 'vboxmanage list usbhosts' and found that the port numbers are different for the two keys, also as expected. Along with just the vendor ID and product ID, I put the port number for the key that is supposed to go into the guest in the USB filter. After a guest reboot just one USB key goes into the guest. But TWO Virtualbox USB filter drivers appear on the host Device Manager, and the other key is not available in the host. It seems to just fizzle off into nowhere.
Socratis' tutorial, section 5 "Common Problems" says for identical USB devices, "There is a technique that might work, but it's so rare and convoluted that it's not part of the FAQ. Start a new topic describing your problem."
Here's the new topic. What's the rare and convoluted technique?
