I just bought a new Kingston DataTraveler DUO for use with the Framework, specifically because it has both Type A and Type C jacks.
[ +0.033118] usb 2-3: New USB device found, idVendor=0951, idProduct=173c, bcdDevice= 0.01 [ +0.000005] usb 2-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ +0.000002] usb 2-3: Product: DataTraveler Duo [ +0.000001] usb 2-3: Manufacturer: Kingston
On my Ubuntu 21.10 system, the device disconnects/reconnects every couple seconds regardless of which port I use. I tried USB-A, USB-C on both left and right side of the machine.

This same drive works in my desktop just fine, so I also tried formatting it on the desktop to see if that would make a difference. It did not.
Based on some other reports I found, I also try
intel_iommu=off but to no avail.
It does work however if I instead plug it into the lapdesk hub. It only fails when it is plugged directly into the framework modules.
Other USB drives seem to work just fine (in the USB-A, I don’t have other USB-C sticks).
