PS/2 wasn't designed to be hot-plugged, but most boards today (all?) support hot-plugging as an unofficial standard. If the board disables PS/2 when it's not plugged in that's fine, it doesn't hurt anything, they just need to reboot like before hot-plugging.

This is very true but it only really happens on old hardware, but still it's not technically standard so users are taking risks to do it. > > if u only use one PS/2 port it is automatic made the second PS/2 hot > plugin depns on the mainboard bios or chip driver for the mainboard > in windows 3.x//NT 3.x/NT 4.x/95/98/ME/2000/XP/Vista/7 > > The question is does anyone want to write sepreate chipset driver for > each mainboard only support hotplugin for PS/2 and add this feature. > > In linux many of the opensource chipdriver does support this feature > but not all. This is not the case to my knowledge. Most chipsets don't even get a single driver installed for them (besides the generic drivers). Stuff like the Intel INF Update tool are simply that, just an INF update to set some registry entries and install (without a driver) some devices that Windows doesn't natively install a null driver for so Device Manager can look nice. None of these devices actually start in the PnP manager's eyes (since they have no function driver and can't be driven raw). > > BestReagd > Magnus Olsen aka GreatLord > (I always read my mail if any one want ask me or known my skype name) Regards, Cameron > > 2011/11/19 Ameen Ross <a.r...@amdev.eu>: >> Linux does support hotplugging PS/2 devices.
