Can we see "lspci -v" output for the external hub you're using?  Obviously the logic clearing TT faults needs tweaking to handle disconnected devices.  But there are two types of high speed hub, and I think they need different logic there.  Seeing that "lspci -v" info will help sort this out.

potential fix: don't clear TT faults in some cases

Try this patch.  It just checks for the "disconnected from TT-per-port hub" case and doesn't bother trying to clear that fault ... on the theory that such hubs will clear fault state along with other per-port state on disconnect.

Hi David,

with this patch scanning doesn't even start :(
BTW this device is laser printer combined with scanner (multifunction). To start scanning lp0 is always removed and than during scan phase I see those errors. BTW they are still the same. To support scanning hplip package needs to be installed.

Same errors with patch:
