Hi,
I recently added a PCIe USB3 Controller Card (StarTech PEXUSB3S2EI, 2
ext./2 int. Ports) to my (old, USB 2-only up to this point) Linux PC
running openSUSE Leap 15.2.
The controller card uses the NEC/Renesas uPD720201 chip.
It works well with all of my USB 2 external storage devices (hard disks,
flash sticks) but not with all of my USB 3 peripherals.
USB 3 flash sticks and a Seagate Expansion 3TB 3,5" external hard disk
work properly.
However, when I connect my Toshiba Canvio Basics 1TB 2.5" external USB 3
hard drive to any of the Ports that the controller card provides (the
internal 19 pin connector is connected to a 2-port front panel), the
device is detected and identified as super speed device, but the disk is
not mounted and the controller dies.
This is what the system log (journalctl -f) says:
Nov 09 15:29:37 ludlum.speedport.ip kernel: usb 2-1: new SuperSpeed

After that, no device connected to any of the USB ports provided by the
new controller is detected, not even one that normally works flawlessly.
Reloading the kernel modules (xhci_pci, xhci_hcd, usb_storage, uas) is
no cure.
Only after forcing a rescan of the PCI bus device with
# echo "1" > /sys/bus/pci/devices/0000:01:00.0/remove
# echo 1 >/sys/bus/pci/rescan
the USB ports are usable again. Or after a reboot, of course.

I tried some USB quirks, namely 't' (NO_ATA_1X) and 'u' (IGNORE_UAS), by
# rmmod uas usb-storage
# modprobe usb-storage quirks=0480:a20c:tu
According to the system log, the quirks are detected/applied when the
drive is connected, but to no avail.
I'm hesitating to apply other quirks, because i'm not an expert at this
and don't actually know what they do.
So I'm afraid they might harm the data on the hard disk.
I use openSUSE Leap 15.2 with the current kernel update version (Linux
5.3.18-lp152.47-default x86_64) but also tried a more recent kernel
version 5.7.0 - same results.
Is there a way to make this Toshiba external hard drive work when
attached to a USB 3 port provided by my STarTech controller card?
Cheers
Matthias
