ET301 locking up computer

Gald you got it installed, Jan.

I spent the last 1.5 hours in the car with Navigation going in SD, with the older driver you posted above, and had zero lockup issues. Before, I don't think I ever got beyond 30 minutes without a lockup. I'll wait a bit longer before declaring this one 'done', but this seems to have been the issue.

I'm not sure what I\we would gain with the new driver aside from having something that's digitally signed (and, uh, seems like that's not worth all that much in this case), so I'm quite content with having this one functioning version.

Welp, it worked fine for the drive out here to Atlanta. We had the car running the entire time...since we drove all night to get here. 10 hours solid before we shut the car off and it didn't lock up once...nothing failed at all..which is a great thing right before finals.

Congrats Jan

I haven't had it lock up since either.

Best of luck at the finals!!!

Hi All, well I stumbled across this issue again in Vista (had some hope that it would work there) and again mailed FTDI support since although the older version works, it conflicts with my OBD-II software whereas the newer driver does not. This time, I got an answer:

Hello,

Is your PC dual core?

If yes, then please copy the attached .sys files over the ones installed in your system32 folder.

I do have a dual core PC

I have not tried these files yet, but it sounds like they've addressed the issue! Files attached.

I'm a bit confused...

This is only to fix issues with Vista?

Or is it to fix issues with ANY Dual Core CPU?

Suddently, I'm running into new issues as well...as in the 301 shows up as an unknown device under USB controllers and SD cannot find it.

It used to be on COM3 but now nothing shows up under COM3.

Not good since I've got a long trip coming up this weekend...ack!

Sorry, here's clarification:this should fix the issue on both XP and Vista.

When I had sent the question to their support I was running XP, so their reply was in regards to XP. Over the weekend I installed Vista and found that it was exhibiting the same issue (locking up). I then tried the files they sent me on Vista and they seem to have fixed the issue also. So - it should fix it on both OSes.

Note: the directions from support state you should place the files in the system32 folder. I found out that for Vista, they need to be placed there AND into the system32/drivers folder in order for it to work (I went into device manager and looked at the properties of the COM port, checked driver details and saw that it was using one of those files in the system32/drivers folder also, so I copied both files into both locations).

Hopefully that clears it up.
