Malware has recently killed off my Acer laptop which was running XP pro and tuning with Tunerstudio.

I was using PL2303_Prolific_DriverInstaller_v110 with a generic USB to serial cable and now running Vista it won't communicate with the MS on any comm port.

Any suggestions?

 

Get rid of vista. I still have nightmares of the first time I tried to hook up my MS using Vista. I gave up, bought an Accer (XP) and never had a communication issue.

EDIT: I had both connection and program writing issues BTW. I would check that the com-ports worked, and they did, but once MS tried to find the port I intended to use it would just take a ****. Once I was using XP I had no problems

 

No vista troubles here.

does your device manager show show the comm port once the cable is plugged in?

 

I hated using Vista with MS.

I forgot how I got it to work...but probably documented somewhere if you search under my screenname. It involved turning off some thing that doesn't let you write in the program files directory and manually moving/deleting a lot of the files that are usually automatically arranged during MT install.

EDIT: OH...connection problems...nevermind.

 

you're talking about compatibly files, that's not even a big deal. Use tuner studio and it save s everything in my docs to prevent the issue.

 

The device is "seen" by device manager when I plug the MS in but Vista acts like the driver isn't installed as it has a nice fat red marker over the "USB D-Controller" device - Im assuming it won't assign a comm port number until Vista thinks the device is installed properly. Windows searching online can't find a suitable driver for it and if I manually update via device driver and navigate to the folder where the driver exists, Vista then tells me that it can't find a suitable driver in that folder?!

 

Welcome to Prolific

 

i'm having the same problem getting my car running, spent all day with tech support at microsoft and the adapter company and they finally said return it and try another, now in the midst of trying a belkin adapter. I also have vista. What about windows 7 with the ms? (sorry for threadjack) I'm running 64 bit vista. what do you guys recommend?

 

The adapter available on our website is known to work with 32 & 64 XP, vista, and 7, The only problems that I'm currently aware of is inability to flash firmware with vista 64 OS only. We have a patch which probably will work that we have released, and I've asked for but have not received any feedback on it. There are no problems using tuning software with any XP or newer OS that I am aware of.

 

Well I finally sorted out the issue.

The prolific driver I was using says it's fine with Vista on their website but it turns out it isn't. Prolific also released a Vista specific PL2303 driver and must have forgot to amend their PDFs. Google: PL-2303 Vista Driver Installer.exe

My MS is now tuning on Vista but over the past 3 days I've had one BSOD while datalogging and one seperate occurance of the known "wacky gauge" demo when data comm streams get confused. (I'm running at the higher 25fps though)

It certainly ran more stable on XP pro but I can live with the odd gremlin.
