Description of problem: On Windows7 guest some USB hardware do not work and guest system hangs when removing it. I guess this is not limited to only the device type i happen to have. Version: VirtualBox 7.0.18 from Bug 33273 In that bug you also see tests i performed, and inxi of host. How reproducible: Always. Tested with kernels linus & desktop 6.6.28 & 6.6.37 While I see no problem with USB flash stick. Steps to Reproduce: 1. Plug in Galep-5 (a chip programmer from conitec.com) 2. Start guest windows 7 in VirtualBox 7.0.18 3. In guest machine menu USB devices, checkmark Conitec (someting) 4. Start the related Conitec software, see it fail to connect. Note it do take minutes to boot normally from plugging in before it can respond. But now it fail desite waiting and retrying. 5. remove checkmark for the device (from 3 above) -> Guest becone frozen, do not even respond to ACPI off from VirtualBox. Workaround: downgrade to VirtualBox 7.0.14 Guest additions can be kept a 7.0.18 for this) I see nothing in host system journal. I guess problem is upstream. I have no time to dig for now, but may test a new version easily.
Another user have reported a very similar behaviour with another USB hardware, other Linux hosts, other MSWindows version, and the problem appear on VirtualBox > 7.0.14 I added my comment, pointing back here, at https://www.virtualbox.org//ticket/22069#comment:2
