Hello, thanks for your fast answer. Am 17.08.2020 11:29, schrieb Gerhard Roth:
The "not on queue" error sounds more like a bug in xhci(4). Could you please try to disable USB3 in the BIOS an see if the problem resolves then.
I disabled USB3 in the BIOS but the connection died again randomly. The difference is, without USB3 there are no errors in XConsole nor in /var/log/messages.
I also tried the HDD with OpenBSD in a ThinkPad W541 with another LTE card (other card but same model) with exact the same results.
To verify that it is no hardware thing, I tried a recent live version of a Linux Mint on booth machines. The download and to run it for some time worked without any connection lose.
