People have varying degrees of success getting the touchpad to work by changing or patching kernels because fixing the driver for one device can break another device. On Linux, the kernel module that handles this protocol is i2c-hid. Or perhaps, it's the other way around? Microsoft has a lot of quirks in the driver so manufacturers cannot follow specs if they are to expect their devices to work (on Windows, until there is one of those "Creator" updates - so named because they create new, never-before-seen bugs). Because device manufacturers often don't read, or perhaps intentionally don't follow, specs, Microsoft has put a lot of little quirks into the driver to make it work. The underlying problem is HID over I2C, an input device protocol created by Microsoft and first used in Windows 8. Sometimes detaching the touchpad, as on an MS Surface or Acer Switch Alpha, can get it working again.
Sometimes rebooting or switching the touchpad on and off can help. But on other computers, the setting may changed only from within Windows. On some computers, the setting may be in BIOS. Neither MS nor touchpad manufacturers actually follow the specs.Īs a result, many touchpads that require the new protocol don't work well with the Linux kernel module i2c-hid. Sometimes kernel updates can resolve the problem (or cause it to return). Should I rather get a PicKit3, power the device from VUSB entirely, and instead of using the MicroStick 3.3V power supply, build my own.MS created a new protocol, HID over I2C. Is the PIC32MX250F128B USB module faulty? Is it because I'm using VMWare? I'll restart into my Bootcamp version of Windows shortly to check.īloody hell, WTH does this thing want from me? Is it because my HID report is wrong, is the size wrong, is HID_RPT01_SIZE incorrect in usb_config.h? Is it something to do with the fact that I have the device plugged in via the debugger USB and the second USB plug, causing Windows to become confused? It's been DAYS that I'v been trying to get this darned USB device working. It's driving me insane, why the hell does this have to be such a bloody battle. I'm starting to think that this Microstick II board is a piece of crap, and it's causing things to go wrong. HIDTxPacket is in fact getting called, but the piece of junk is still persisting with its f-ing Code 10 error.
I can't set breakpoints in MPLABX, and halt the MCU to investigate the issue, because of USB clock timing requirements, so really stuck as to how I can troubleshoot and fix this. I also managed to get the following from the USBLizer trial version: What I've done is light up an LED on Pin 2 (RA0) when USBDeviceState = CONFIGURED_STATE, and all I know is that the device is in CONFIGURED_STATE, as the LED lights up a few moments after the device is plugged in. The Microstick II doesn't appear to have the best debugger, so debugging is limited. I'm testing my device on both Mac and Windows 7 via VMWare.

The full contents of main.c is at my GitHub repository This is about the furthest I've come with this project ever, but I'm face to face with a brick wall, that won't budge. I've also set the descriptor size to 28 bytes in usb_config.h: The above represents a Joystick with one button, so I'm trying to start small.

The device enumerates, and I'm able to see that Windows 7 and Mac OS X is able to identify the device. (Code 10) with a USB HID device I'm building. I'm trying to fix an error This device cannot start.
