| 143182 | 2003-05-11 09:50:00 | Hi all I am having mouse troubles (PS/2) with my new KVM switch. My model is the same as this 2 port Auto KVM switch (www.dse.co.nz), but I didn't get it from DSE. I connected the two PC's (PC1=XP; PC2=ME/Lycoris) up OK (everything working 100%) and could switch between the two OK initially, but then after 10 mins to 1 hour the mouse starts behaving very erratically. It either goes very slowly or jumps all over the screen in a random pattern when you try to use the mouse, basically rendering it useless. Then things gets even more exciting when the various windows I have open take turns at randomly being the active window, despite actually working in one at the time. The mouse behaviour seems to deteriorate the longer it continues, until you are only left with keyboard control. It does this on both PC's. The Linux Lycoris is a fresh install made when the KVM switch was in place. It too displays the same behaviour. Things that I have tried: * checked all cables are firmly in their correct places * rebooted both PC's which *sometimes* reverted the mouse back to normal * let the KVM switch rescan the PC's (made no difference) * On the XP machine, the device manager shows no conflicts with the mouse * Removing the KVM switch cures the mouse As it seems that only the mouse is affected, could it be a fault within the switch? Has anyone else with a KVM switch experienced this problem? I am running out of ideas to try now. Any suggestions appreciated Thanks Jen :-) |

| 143183 | 2003-05-11 12:15:00 | My thoughts are that it may be the mouse type... Try borrowing another mouse for a while.. different type of course, and see what happens. Perhaps updating the Drivers?? |

| 143184 | 2003-05-11 12:24:00 | Maybe it is not emulating the mouse properly. What happens when you power the computer on when you're not switched over to that computer? | -=JM=- (16) | ||
| 143185 | 2003-05-11 12:48:00 | I tried that, and the PC just started booting and then ended up turned off again?? (a bit hard to see what was happening with no monitor on). I imagine it didn't like having no mouse/keyboard visible. I am sure the instructions said not to boot up without switching over to that PC first, but as I have seemed to misplaced the instructions, I cannot be sure. I will borrow another non optical-scroll mouse tomorrow as Chilling suggested and see what happens with that. The funny thing is, that it does work perfectly for a period of time, before the mouse loses the plot ?:| Failing all this, I will return the KVM switch and get a replacement to try. Cheers Jen |

| 143186 | 2003-05-11 12:58:00 | Yes, you do need to be switched to the PC that you are turning on/rebooting, otherwise Windows/Linux tries to be a clever OS (Unless you've turned off kudzo in Linux, but I dont know how Lycoris treats it) and take notice that 'Hey - There's no mouse or keyboard plugged in right now, how about we remove them from the hardware list seeing as they dont exist.. just a second... yep, and they're gone'. Not the best, plus your PC might throw a wobbly when its starting up, with a warning that there is no keyboard. That can be disabled in the BIOS though :-) Hope this helps Chill. |

| 143187 | 2003-05-11 20:21:00 | It should emulate the mouse and keyboard seeing that it is an automatic KVM. I know that the only times I've had problems with the mouse with mine is when I've done the OS install without being switched over to the correct computer. | -=JM=- (16) | ||
| 143188 | 2003-05-11 21:23:00 | My identical KVM switch allows either PC to boot up just fine without being selected on the KVM. The instructions (from memory) actually stated that it presented appropriate signals to simulate monitor/keyboard/mouse. |

| 143189 | 2003-05-11 21:51:00 | Don't want to put you off track, so to speak, I don't have any experiece of KVM switches and it seems the posts are plausable . But if all else fails, as you state try another rodent . It could be a defunct mouse rather than a "Rampant" one . Just nerves twitching in the last throes of life . Thats the way my trusty old MS mouse went anyway . just as you describe, windows popping up all over the place and pointers with minds of their own (thought I'd been mind reemed or my wife was slipping something into my steak & kid') . Tried a new home for it but the same symptoms resulted . So you might have to administer last rites in the vegi garden and get a new one . Plenty around this time of year though . Cheers Murray P |

| 143190 | 2003-05-12 06:31:00 | Thanks for all your comments :-) I have seemed to have cured the problem now - a new mouse fixed it! It is still an optical scroll mouse as it was a spare one I had lying around . The previous mouse (R . I . P) chose to pack its bags and head out of town (being made to run through a KVM switch was obviously the last straw for it :D) Sorry Murray, I don't have a vege patch but my cat has gratefully disposed of the corpse instead :D Thanks again everyone Jen |
