Can't get USB device to work with an Ubuntu host & Windows XP guest VM

[influx3k]

Having an issue where I can't get a USB device (ROM programmer) to work with an Ubuntu 26.04 host and Windows XP SP3 guest VM. Running VirtualBox 7.2.6. I have the latest extension pack and guest additions installed. This used to work perfectly on a previous MacOS host; I've moved this VM from an old MacOS host to a new Ubuntu 26.04 installation on a new machine. I have a USB Filter setup for it and the latest drivers installed for the device in the VM. I have the device enabled within the VM and the Windows Device Manager seems to recognize it, however the associated software doesn't seem to be able to find it. When I unplug the device, I do get a window that says "USB Connection Lost!" and when I plug it in, the software does seem recognize it, at least partially, as it pops up a window where it's attempting to "initialize it" but then later says "initialization failed".

I must be missing something here. Could it be that Ubuntu is not letting the guest OS take control of the device? Any help would be greatly appreciated!

I got it to work by choosing USB 1.0 in VirtualBox. The device is USB 2.0 compatible and I had it setup that way when I had it on MacOS. Anyone know why or how I could get it working with USB 2.0?

No idea why USB 1.1 works better for you than USB 2.0 - both should be similarly expensive to emulate. From a VM there is no speed limitation of USB, so I wouldn't expect there would be a significant performance gain by switching. There would be for switching to USB3, but Windows XP doesn't have drivers for that.
