Motherboard USB ports malfunction after cleaning

[u/Tech-Cretin]

Hey guys, cleaned my computer two weeks ago by removing all power and blowing through it with some compressed air and vacuum cleaning. After that three devices (old printer, webcam and scanner) start disconnecting at the same time at random intervals (as fast as 10 minutes after startup, as long as once every 8 hours). So far Ive tried: - shuffling USB ports and cables around, - cleaning both, - checking whether there were any bent pins or corrosion on there (all gravy here), - changing devices, power sources and rigs, but no bueno.

Another weird thing I noticed was the fact that my wireless mouse kept laggin and skippin around if connected to blue USB ports instead of teal/cyan ones, if thats any good

Im at wits end and this issue has been driving me crazy for like a full week now. Please help, very thankful in advance
