well, i dusted off my ancient 6200C and tried it with current sane cvs- i get:

...
[hp] sane_start called
[hp] hp_GetOpenDevice: device libusb:003:006 is open with fd=0
[hp] Start downloading parameters to scanner
[hp] sanei_hp_optset_scan_type: scantype=0
[hp] scsi_flush: writing 2 bytes:
[hp]  0x0000  1B 45                                            .E
[hp] scsi_flush: writing 7 bytes:

[hp] scl_inq: read failed (End of file reached)
[hp] scl_errcheck: Can't read SCL error stack: End of file reached
[hp] scsi_close: closing fd 0
[hp] hp_IsOpenFd: 0 is open
[hp] scsi_close: not closing. Keep open
[hp] sane_start will finish with Error during device I/O
scanimage: sane_start: Error during device I/O
...

which seems to be a failure even sooner than yours. i do not know for
sure if this thing works anymore, but it did when i last used it a
couple years ago. i dont have the docs or the time to dig into this,
but perhaps someone who knows SCL is listening?
