Hi!

Today I tried my USB scanner, an Epson Perfection 2480, again on
NetBSD-4.99.20/amd64 (built on June 5). It has trouble downloading its
firmware.

The last try before that was on May 12 on NetBSD-4.99.19/amd64 built
on May 1, where the scanner still worked.

I'm not sure if I should suspect flaky hardware or NetBSD
problems. Between the two tries, the scanner was just put in a dark
corner and fetched again.

Attached is the log of xsane with SANE_DEBUG_SNAPSCAN set.

Any ideas?
 Thomas
