USB ERROR: Failed to set configuration - Device or resource busy

[Carl M]

I am getting the error above when I attempt to configure digitemp on a fedora 33.

Details below.

Any ideas on what might be the issue, or things to check, would be most appreciated.

Digitemp has been used successfully for several years on a NUC7i7 with fedora 29.

Using digitemp on the fedora 29 required the command "modprobe -r ds2490" to be

executed at boot-time.  I did not have to modify anything (permissions, etc) related to the USB to get it to work on fedora 29.

The sensors are ds18s20+PAR

The adapter is USB DS9490R (chip ds2490)

----------------------------------------------------------------------------------------------------

On fedora 33,

Command below executed on same NUC 7i7 with fedora 33. (I did install a 1Tb SSD nvme instead of a SSD sata 1Tb drive)- same sensors and adapter.  digitemp ver 3.7.2 for fedora 33.

I did not use the "modprobe -r ds2490" with fedora 33 because it will not boot if I use the command at boot-time.  If I use the command after boot, the pc becomes unresponsive and requires power reset.

>digitemp_DS2490 -i -sUSB -q -c /etc/.digitemprc

The command below was executed twice on the fedora 33, once using the .digitemprc config file that was being used on Fedora 29 successfully, and once without that config file.  Error message same in both cases.
