trying to create plugin for UltraSconi, getting driver error

[topix]

EG 0.4.0.1397

I'm trying to create a plugin for JBmedia UltraSconi based on WinUSB. The driver is successful created and installed. After the restart of EG i get an error, that the driver could not be opened.

Any hints/tips/ideas what to try out, or check out?

[Bartman]

just wondering.
Did you get any specification from JB? I wanted to make a plug in years ago and even received a sample but later JB was not willing to give any support.

Does this device actually register as an HID device?
The MS MCE remote for example can also be assigned to the WinUSB.sys driver, but it will not work, because this remote is not a generic HID device.

[topix]

Yes, it shows up as a HID. With the generic HID plugin i get events like this:

Code: Select all

HID.001C181B1936181C18
HID.001C181C181C323618
HID.001C181C181C181CFE
HID.00FF00000000000000

And the events are not always the same for one button.

No, i haven't contacted JB for now. I wanted first see if it works the WinUSB way.
It's sad that he doesn't want to support you But you say it's years ago, maybe JB changed his mind?

Where does the GUID for the AddDevice call come from? Doesn't look like you have created a new one.

[topix]

The GUID is from Windows Device Manager. I thought the GUID i created is just for eg.RegisterPlugin. Should i use the same GUID for AddDevice and RegisterPlugin?

[Bitmonster]

No, you must create a unique one for every AddDevice call.

[topix]

Ok, no more error, but i get no data from it
Well, i think i should write JB and ask him for help...

[Bartman]

Dann viel Glück.
Ich teste aber gerne mit.

@Bitmonster
hat es eigentlich einen Vorteil den WinUSB Treiber statt HID zu nehmen, wenn das Gerät sich nicht als Tastatur und/oder Maus ausgibt?

This is an english forum, so please continue in english.

In this case most likely not. It might have a better perfomance to use WinUSB, but WinUSB has the drawback of needing a driver installation. So for this device I would stay with eg.WinApi.HID.
