No idea, what exactly is going wrong. This message comes from the
atp870u driver; obviously something is broken at a very basic level.
The cause can be the scanner, the SCSI host adapter, the atp870u
driver -- or simply a bad SCSI cable or missing SCSI bus
termination. If you have other devices connected to the same SCSI
bus, they could be the cause of the problem too.
If possible, try different cables and another SCSI adapter, or
connect another SCSI device to the Acard adapter to get a better
idea, where the error might come from.
