Hi,
a new hp-backend V1.01 has been released. It is available in CVS and at
http://www.kirchgessner.net .
It adds a workaround for the problems with Buslogic SCSI cards which
give an "Error during device I/O" during startup. A new option
option dumb-read
is supported in hp.conf.
Without the option, the kernel driver reports an error when an attempt
is made to read more bytes from the scanner than available (i.e. try to
read 16 bytes, but only 7 bytes are available).
With option dumb-read, small amount of data is read bytewise until the
requested number of bytes has been read or an error occurs. If an error
has occured and data has been received, the error is ignored and the
data is processed.
Please give the backend a try and report problems back.
