USB Drivers for HEX-COM+CAN (W98) Broken:-(

Hello,

With my HEX-COM+CAN system and VCDS 8050, I wanted to start a logging session: ignition on, logging started, then start the engine - and the Lappi (Elitegroup without its own battery) turns off due to undervoltage because I forgot to connect the buffer battery .
Approximately 2 seconds later, the engine also stalled, but it started normally again after turning the ignition off and then on.

After restarting VCDS as usual after the Scandisk process, it now constantly searches for the USB driver for the interface. If I interrupt the search, VCDS runs up to the module selection window, but a single click immediately results in a large error window – the same thing happens with the previous version 7041(?).

I haven't started trying to repair the software yet. Since I'm not very skilled with computers, and I tend to make things worse by fiddling around and causing even more damage, I'd rather ask here directly what to do .

Hi Ulf,

Your rescuer might be the Device Manager. Try installing the Ross-Tech Direct driver.

Best regards, Rainer.

Thank you.
"Is the driver located in the 8050 directory on the laptop (I don't have time to check right now), or do I need to download it from Uwe's website?"

Meanwhile, I've come up with a possible Plan B:
"Uninstall version 8050 and then reinstall it" (making sure to back up the logs and my labels beforehand).

Is that also conceivable, or would a failure be foreseeable?
Or should I uninstall all approximately 5 previous versions of the professional software at the same time?

Hi Ulf,

Yes, the driver is located in the installation directory.
Reinstalling everything doesn't help with Windows 98, in my opinion. The pre-installation of USB drivers probably only started with later versions of Windows.

Best regards, Rainer.

I found the following there:
RT-USB.dll
RT USB9x.inf
RT USB9x.sys

When using the automatic driver search *) for "USB<->Serial", I correctly specified the installation directory as the storage location. The "OK" button was also active, which means that something apparently useful was found in the specified storage location.
"However, the response was 'No driver could be found'."

I then tried entering the installation directory of the previous version, 7041, as a test, but the result was the same.

I didn't mean the usual reinstall process, but rather the proper removal using the uninstaller (deinstall.exe) ...?

Okay: I still have Windows 98SE on my laptop .


*) when plugging in the USB cable (without any red or yellow problem symbols appearing in the device manager's hardware tree), or after clicking "Refresh" in the device manager.

Hello Ulf,

You must either remove the USB-Serial driver in Device Manager or use the Ross-Tech Direct driver with the files mentioned above.

If you want to continue using the USB-Serial device, you must specify its installation directory as the driver directory (i.e., the location where the archive was extracted).

The same might apply.

Best regards, Rainer.

. Hmm, and which one exactly should I delete (see attachment)? None of them show any recognizable indication of Ross-Tech or similar in their properties.

BTW: The device manager on my home PC (also running Windows 98SE) shows the exact same drivers as the one you clicked on, and the Hex-Com CAN interface has never been plugged into it.

I tried that, but... see above.

Is that the RT-USB.dll file that was mentioned?
But how do I manually bind it under W98SE?

Hi Ulf,

You will only see the diagnostic cable in the Device Manager if it is also connected.

Yes.

Plug in the cable, then right-click on the device icon in Device Manager, select "Properties," and choose the driver.

The items in your picture are "normal" and are part of PC hardware.

Best regards, Rainer.

This works for other USB components, but it doesn't work (anymore) with the Hex-CAN: the Device Manager remains unchanged, regardless of whether the ignition is on or off.

I've temporarily installed the 8050 software on my home PC as well: at least this way, the Hex-CAN is displayed as a yellow question mark -> attachment.

If that doesn't work: After correctly specifying the installation directory (on the home PC), you still get the message "no driver for the device could be found."
In the Lappi device manager, I can no longer find the (plugged-in) Hex-CAN device .

And now? Did I damage the interface by abruptly shutting down the laptop (and if so, why did it survive multiple times before)?
But as I said: something is still alive in there, because when you plug it in, the driver search starts immediately .

*g*

The yellow question mark indicates the HEX-USB+CAN. Please also open the list of USB devices at the bottom.
It's best to remove the serial port setting at the top and then install the correct driver by right-clicking, going to "Properties," and selecting "Install another driver." Before doing this, select the device you want to modify by left-clicking on it.

I meant connecting the diagnostic cable to the PC, not to the car.

Best regards, Rainer.

Bitte auch mal unten bei den USB Geräten aufklappen . . . Mit 'anstecken' meinte ich das Diagnosekabel am PC anstecken, nicht am Auto.

Und genau dabei tut sich nix, wenn ich das Hex-CAN ans Lappi stöpsele: ich sehe nur die 4 normalen Treiber wie oben im 1. Adepicted.

If I cannot do this for the reasons mentioned above: The Hex-CAN device does not appear anywhere in the laptop's Device Manager.
Sorry that the dialogue got so long; I hope I managed to convey the message.

Hi Ulf,

Call me; I'll send you my number via private message.

[Edit] It appears that the diagnostic cable is faulty. [/Edit]
