[sane-devel] libusb : Error during device I/O

["Günter Haus"]

Hi Oliver,

>(04a5:20b0) 
I've allready used it by symlink, now I've copied it & checked it twice: 
unfortunately without luck. The error 
[snapscan] sense_handler: Hardware error. (0x01, 0x00) 
remains!!

Scanner works perfectly under windows using the same PC.  
 
Would you have any other hints? What could be a strategy to find the 
source of this error.
