Cool ! Can you tell me what change you needed to make for that? GlovePIE users would be very grateful.


Looks like you may have figured it out, but here's what changed in 0.9.1.

When using the Microsoft stack, it seems that HID_SetOutputReport works, but HID_GetInputReport always returns garbage (without reporting that it failed). To get around this in 0.9.0, WDML used SetOutputReport to send reports to the Wiimote and used ReadFile (on a handle wrapped around the HID device) to read from the Wiimote. Some non-MS stacks don't seem to support SetOutputReport however, so in 0.9.1, SetOutputReport is called and if it fails, WriteFile is used instead to attempt send the report.

It would be nice to know why exactly this support is missing in different stacks, but I haven't seen much of any info along those lines.

HidD_SetOutputReport returns success on BlueSoleil, but doesn't work. So MiiTransfer 0.90 and 0.91 won't work on BlueSoleil. Also HidD_SetOutputReport doesn't exist before Windows XP.

Reading the serial number of the Wiimote on BlueSoleil will reboot the computer, so don't try it without user confirmation.

GlovePIE assumes it is running on BlueSoleil, and uses the WriteFile method, unless the user manually chooses the Bluetooth Fix menu which makes it try SetOutputReport (if it exists) and if that fails then uses WriteFile. The Bluetooth Fix menu stops it working on BlueSoleil.

I think HidD_GetInputReport is designed to request a specific report and you need to fill in the report number first. I haven't tried it.

Does WriteFile fail on MS? or does it succeed and then not work?

I just installed bluesoleil to see what's going wrong, but MiiTransfer 0.9.1 works fine. It does print a garbled string for the device name, but reading and writing still work as normal, and reading the device serial isn't causing a BSODs (though it did when I tried running an HID sample application that reads the serial).

Are there still problems with bluesoleil? The version I tried is the downloadable trial version, not the bundled version. Could it be coming down to the BT hardware that is used with bluesoleil?

I take that back, I had forgotten that the version of MiiTransfer I have locally is not 0.9.1, but a more recent version modified to only work on Bluesoleil. Well, it does that, but it doesn't work on the MS stack anymore.
