Once again, a strange hardware problem has "hit." At least it's on my own box and not someone else's. I've spent off and on the past 2 days checking everything I can think of, searching the Net. as well, trying to find the answer as to why an Epson Precision 4990 Photo printer can't be configured by Yast.
It IS seen by the system, as I checked with hwinfo --usb and it's found, so I know that it does respond to the USB port. I have the 3 iscan files installed, which are supposed to provide FULL function for this scanner, yet, when I use "edit" in Yast, an entry is entered for "epson" that says the scanner can't be found. I double checked that it can't be used with xsane and iscan. The is the first time I've not been able to configure a scanner that is seen by the system and drivers are rated as "complete" and listed in Yast.
I hope someone knows a "cure" for this! I'm using 10.3 64-bit.
Tanks in advance!
As with your problem a couple of weeks ago, I am unable to give you a definitive answer but can offer this comment. Only last night I read an article (about power supplies) which is pointing out that with all the new CPUs and video cards most of the problems (such as you may be experiencing) are/maybe caused by poor PSUs. El cheapo PSUs -- and these do not necessarily include those which are pretty high priced! - even though rated as being able to high wattage demands may not be able to do so and therefore cause 'you' problems. As a guide, I have been using the following table to work out what sort of wattage "my" PSU should be able to handle: COMPONENT WATTS MOB 15-30 CPU- Low end 20-50 High end(1) 60-100 RAM 7W/128MB PCI card 5 Network card 4 Floppy 5 Graphics card- Low end 20-60 High end(1) 60-100 CD/DVD/RW 10-25 IDE HD 10-30 SCSI - 10K-15K 10-45 To the TOTAL watts arrived at using above, ADD 30% to arrive at the wattage needed to be handled by the PSU. (Note1: these figures are applicable BEFORE the latest dual-and quad-core CPUs and also before the latest high end video cards came into being. Check their tech data to see what wattage they draw.) While the above figures give you a ball-park figure for what wattage your PSU should be able to handle, it then becomes a matter of ensuring that you get a PSU which *will* be able to 'deliver' because many PSUs (including expensive ones) claim one thing but simply do not 'deliver' when it comes to the crunch.
