In reply to norm doty's post on June 14, In reply to Chris - Support Engineer's post on October 7, Hi all, I did try the solution given in the above link and it does not work for me.
Disables the USB port. Data reception is lost. Installs the driver automatically. I want to know, if there is anyway, Windows 7 could Not detect a device on the same port if something else is already connected to it.
Similar file to Boot. Any help is appreciated, Thank You. In reply to Yodha's post on October 29, Yodha, It looks like your problem is similar, but differs from the original question. I had the same problem, c ursor sometimes jumps all over the screen Here's the fix: Open Regedit. In reply to Rawleigh's post on January 28, Will give this a try In reply to WayneJD's post on January 28, The gps works if i can correctly remove the ballpoint from the device manager, but on a touchscreen in my car it is pretty difficult since the incorrect driver moves my cursor and clicks mouse buttons as the NMEA data flows over the com port.
Now, here's the real problem: With my old XP Pro system, you could open the control panel, open device manager, and expand the tree - and then open mouse and pointing devices, and wait Then, you could get enough control to hit "OK" to confirm Sadly, with Windows 7, you can try this trick, but the sorry-thing wants to keep checking enumeration, and within seconds, it overrides the GPS enumeration and goes NUTS again. XP didn't do this?!!! How about being able to uninstall that complete driver?
I mean, you can do that now By the way, this is also a majority issue with anyone using plug-in GPS'. I had the same problem, c ursor sometimes jumps all over the screen. Here's the fix: Open Regedit. I found this on a website for a program to help with gps. Worked like a charm for me. There is a reg file that will do the editing for you also. I've made the registry change from above, and it works for awhile, but for some reason the reg setting keeps reverting back to a 3.
I'm also sometimes getting a bluscreen that I believe is also caused by the GPS being connected at boot. After the BSOD is when the reg setting reverts back to 3. Using Win7 ultimate on a variety of machines, when I plug in a 'USB' GPS the system does two things: it installs the support for the USB-Serial device, and then it using 'serenum' apparently begins mistaking the GPS for a serial mouse, and 'detects' and installs the microsoft serial ballpoint.
The GPS is consistently being enumerated by the system as a "serial ballpoint mouse". This has been reported by numerous people in numerous forums on numerous configurations over multiple windows versions. When is Microsoft going to fix this? This is not a GPS issue. This is not a serial device issue. This is not a USB issue.
This is, pure and simple, a Microsoft issue. Removing the 'upperdrivers' entry for serenum might do the trick, but the registry keys are not writeable now in Win7. Thanks, Microsoft.

It drove me mad for 2 Hours! Is there any kind of documentation on this registry entry? Right now, 3 and 4 are totally magic numbers to me. Microsoft has documentation on the sermouse node , but not on the actual Start element itself. You are my hero! I was ready to throw away my computer I was so frustrated! Show 1 more comment.

This is the best solution in my opinion. Once disabled and connecting the device no reboot necessary which is another plus there was no activity until a program which uses the device is started.
I have encountered this Windows bug myself. All ports on the computer will be shown. Do this for all ports on the computer. This should hopefully work as an universal solution.
Lundin Lundin k 35 35 gold badges silver badges bronze badges. Thanks for the suggestion. I'd prefer to avoid any user intervention by changing the protocol on our device so as not to confuse Windows, but if that doesn't work out then at least I have an official workaround and "bug" acknowledgment to refer to. I've implemented tinman's suggestion along with repackaging our data as 7-bit ASCII now and have yet to see the problem again, though to be honest it never did appear all that frequently.
Because Windows assumes that this ancient Microsoft mouse has a certain baudrate. I have encountered the problem when using a faster baudrate than , the data can suddenly get interpreted as something coming from the mouse. When that happens The mouse will move all over the screen at the speed of light, clicking everywhere!
Anything can happen. I wouldn't risk that, I would use the tool Microsoft recommends in that link. Thankfully we're using a FTDI chip with a virtual serial port driver instead of a real serial port.
So there's no risk of the data being mangled through an invalid baud rate setting. Jon: on Windows 8. David Refoua David Refoua 3, 1 1 gold badge 28 28 silver badges 51 51 bronze badges. That may work for you personally, but it does not address the problem of the original question, which requires a solution that works for end users and not only developers willing to modify the system configuration.
ChrisStratton True, and I may not have posted this as an answer but I merely wanted to provide a quick solution for devs like me Googling this issue. I used a ms delay after serial connection to prevent Windows detecting my device as a mouse, instead. Worked for me just great! Thx — Paul Allsopp. ChrisStratton This is not a developer fix, this is a fix for anyone. Users should have a basic understanding of what Device Management is.

DRS David Soft If your design can include a proper USB interface using some appropriate device class for your device, then most likely that for end-user things of course this also demands creating drivers.
If it is not, then I think it is better to stick with an ordinary DSUB-9 connector RS , that's more robust if you later wanted to use the device combined with some other microcontroller-driven device for a more autonomous system.
