[opensuse] Once again..........
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! Fred -- This message originated from a Linux computer using Open Source software: openSuSE Linux 10.3.

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.

Just to back up Basil's comments... I had loads of odd and unsolvable problems with peripheral devices (like printers), and randomly failing hard drives (that worked fine when put into a second test machine). Very frustrating problems that I knew should not be a problem, or should be easily solved. I ended up replacing the PSU with a BeQuiet 600W (http://www.be-quiet.net), and that cleared it all up. The computer has been rock solid stable ever since. Now the only issues I have are all the ones I create by tinkering.

Frank, Let me second Clayton's remarks. I had a mandrival server that I swore had a corrupt kernel or was possessed by the devil. It ran beautifully for almost a year. Then over the course of several months it randomly began locking up more frequently. Sometimes with kernel errors spewed all over the console, sometimes with drive errors, and sometimes for reasons only it knew of. After testing everything but the psu (because it was Antec, and older Antecs were all bulletproof) I decided to blindly change the psu. As replacement PSU from a price/performace stand point, I have always liked the Thermaltake W0100RU 500W RT. Usually runs about $60 US and will easily support a modern CPU, 4 large drive, dvd, video, and everything else I use. After installing the new psu, the sever is back to being rock solid again. http://www.newegg.com/Product/Product.aspx?Item=N82E16817153052 (shown as the best price from) http://computers.pricegrabber.com/power-supplies/m/35656978/ As for service/price/RMA response/etc I have always like newegg. (No I don't work for or endorse anyone, I just know who I have dealt with in the past and which vendors were honest) May not be your problem, but I hope that helps. -- David C. Rankin, J.D., P.E.

... Epson Precision 4990 Photo ...
I don't know about such a model. Up to now I only know about an "Epson Perfection 4990 Photo".
I have the 3 iscan files installed
Which 3 _files_? I guess you talk about RPMs? If yes, which exact RPM package names?
which are supposed to provide FULL function for this scanner,
From where do you have this information? As an "Epson Precision 4990 Photo" is neither listed in YaST nor can be found via http://www.sane-project.org/cgi-bin/driver.pl you must have got this information from somewhere else.
I'm using 10.3 64-bit.
Did you read the info about "iscan" on 64-bit hardware in YaST? For example the "Epson Perfection 4990 Photo" is shown in YaST with driver "epkowa" and the info shows "requires DFSG non-free iscan-plugin-gt-x750" and when you try to set it up in YaST, it shows this message: --------------------------------------------------------------- The package iscan should be installed but it contains proprietary binary-only i386-only software. Therefore it is only available for i386-compatible architectures and it may cause problems on AMD 64-bit (x86_64) systems. --------------------------------------------------------------- The "DFSG non-free iscan-plugin-gt-x750" is provided in the package iscan-proprietary-drivers and the RPM info is --------------------------------------------------------------- Proprietary Driver Libraries for Image Scan for Epson Scanners The proprietary binary-only i386-only libraries are provided (in object code form only) ... --------------------------------------------------------------- This means that the iscan-plugin-gt-x750 doesn't work on a plain 64-bit system - it might work if all required 32-bit libraries are installed on your 64-bit system and it should work if you install a 32-bit openSUSE on your 64-bit hardware. The plain iscan (without a iscan-plugin-*) should work o.k. on a 64-bit system if all required 32-bit libraries are installed (in particular sane-backends-32bit.rpm) but I don't know the exact details for each possible case when which of these proprietary driver stuff works or fails. Therefore I don't want to show an ultimate "this device does not work on your system" message in YaST.
