Everything was clicking along just fine-- the system even auto-recognized and automatically installed a new USB-connected printer (HP DJ D1520).
Then, I triggered "automatic updates" and ended up with, among other things, a newer kernel.
Suddenly the system no longer recognized the printer, the PDA applet reported conduit-synch failures (PDA is USB-connected), and about six weird messages all along the same theme as the following started appearing at boot:
[22.049917] usb 2-1.3: device descriptor read/64, error-110
[87.977775] hub 2-1:1.0: unable to enumerate USB device on port 3
Another weird thing is, the system still recognizes and mounts my external HDD and my thumb drive, both USB connected.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I'll post the output of dmesg if anyone wants it, but it's really
I've Google'd for and found solutions for this problem, but none that I find effective or even understandable. Many thanks for any help anyone can render.
