The same error keeps coming with Tumbleweed snapshot 20220227 when plugging in my EPSON Perfection1640 scanner.

Looks like a general USB problem of the Etron EJ168A USB 3.0 and nobody seems to care as far as I can see. :-( https://www.spinics.net/lists/linux-usb/msg211162.html

SuSE Tumbleweed with newest updates and upgrades.

5.7.1-1-default #1 SMP Wed Jun 10 11:53:46 UTC 2020 (6a549f6) x86_64 x86_64 x86_64 GNU/Linux

Just recently started to give error messages when plugging in e.g. USB Headsets, Arduino Uno into some Exsys USB 3.0 hub.

This was working fine in Tumbleweed before and in e.g. SuSE 13.1.

The error message is e.g.: [...]usb 2-1.4.3: new full-speed USB device number 10 using xhci_hcd [...]usb 2-1.4.3: New USB device found, idVendor=2341, idProduct=0043, bcdDevice= 0.01 [...]usb 2-1.4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=220 [...]usb 2-1.4.3: Manufacturer: Arduino (www.arduino.cc) ...serialnumber... [...]kernel: usb 2-1.4.3: Not enough bandwidth for new device state. [...]kernel: usb 2-1.4.3: can't set config #1, error -28

This error message started on Jun 04,  after making an update (zypper up) on June 3rd.

Not the exact issue, but I began seeing USB strangeness with 5.6.3 where on plugin the journal output no longer displayed the assigned device attach point, e.g. /dev/foo...

For 5.7, phoronix summarized the USB changes here: https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.7-USB-Changes

I don't have an Arduino, but have several TI micro-controllers that use a USB-C type connector. Perusing the 5.7 changes, there were a couple related to USB-C specifically.

you might consider your tone when requesting or not, help.

and trimming and top posting and ... or not.

Maybe I should not post, when problems with openSUSE are piling up and my tone of despair comes through. Sorry for that.
