QuickUsb driver not working with linux kernel kernel-4.9.5-200.fc25.x86_64 #149

Everything seems to be in order with kernel-4.8.6-300.fc25.x86_64.

An excerpt from dmesg

[  249.308465] usb 1-3: USB disconnect, device number 2
[  255.052758] usb 1-3: new high-speed USB device number 7 using xhci_hcd

[  255.222425] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0

We got the idea that the kernel might have been the issue from https://patchwork.kernel.org/patch/9360849/

Not sure what we might want to do here, except for seeing whether everything works with new kernel.

This is probably very serious. Doing some research it seems like the qusb driver is just incompatible with the default configuration of the new Linux kernels.
