![]() This driver implements support for legacy serial mice along with serial plug-and-play. It turns out that mouse detection in Windows is normally handled by the serenum.sys filter driver. You then need to restart the computer, which should now start correctly and not attempt to discover a serial mouse. Specifies that the service should not be started.Ī reg edit command would be as follows: REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\sermouse" /V Start /T REG_DWORD /F /D 4 Specifies that the service does not start until the user starts it manually, such as by using Device Manager.Ĥ Disabled. Specifies that the service is loaded or started automatically.ģ Manual. ![]() Specifies that the driver is loaded at kernel initialization.Ģ Automatic (loaded by Service Control Manager). Components of the driver stack for the boot (startup) volume must be loaded by the kernel loader.ġ System (loaded by I/O subsystem). Here is a list of all valid Start values: 0 Boot (loaded by kernel loader). I just encountered this problem myself on Windows 7 Professional 圆4, and a solution that worked for me was to go into the registry and edit the following value: Location: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\sermouseĬhange Value to 4 and it will stop this problem occurring. Would sending only 7-bit ASCII suffice? Are there any other devices I need to worry about being detected as? The only problem is that I'm not quite certain what patterns to avoid.Īpparently Microsoft's Mouse protocol consists of packets of four bytes where the MSB of the first is set and that of the last three is clear. Instead I'd like to avoid the problem by changing our protocol to not send any data which may get us misidentified as a mouse. Especially not when the fix is dependent on the Windows version and the user may well be using a bus mouse. That it is a lot to demand from our users however and I'd rather not have our application messing around with the user's registry. The problem is that the data we are sending occasionally gets incorrectly identified by Windows as a bus mouse, after which the "Microsoft Serial Ballpoint" driver is loaded and the mouse pointer starts jumping around on the screen and randomly clicking on things.Ī bit of Googling reveals that is an old and well-known problem with serial devices where the usual work-around is a bit of registry hacking to disable the offending driver. This makes use very difficult because the mouse is never displayed where it actually is and i have to estimate my clicksĬlarity: the issue I have is on a full install, not virtual box.I'm working on a device which communicates with a PC through a (virtual) serial port. so the mouse is actually in its original location, but it's displaying offset and flickering back and forth from its down/right position and its correct position ![]() It seems like a display issue because if i hover over a link or the x to close a window the cursor will settle in it's down/right position, but the whatever im hovering over will still act as if that's where the mouse is, and clicking still works on the item. The jump is maybe 15-20 pixels down and to the right it does not jump when typing, i've done a lot of searching and cant find an answer, it tends to happen most when i move the cursor Since then i've done all the usual updates but ive had an issue with my cursor jumping. I updated to 12.10 beta 1 when it was released (coming from 12.04 fresh install, i skipped the alpha releases of 12.10) ![]()
