I'm making an attempt to copy TUSBPseudoHIDInterface into libusboop.pas. I've
made the recomended name changes and then tried to compile it. Some things I
found like the names changing from things like
PUSBInterfaceDescriptop to Plibusb_interface_descriptor
are pretty obvious, but just taking a guess on other things like:
changing:
if (EP.bmAttributes and USB_ENDPOINT_TYPE_MASK =
USB_ENDPOINT_TYPE_INTERRUPT) and
(EP.bEndpointAddress and USB_ENDPOINT_DIR_MASK <> 0) then
To:
if (EP^.bmAttributes and LIBUSB_TRANSFER_TYPE_MASK =
LIBUSB_TRANSFER_TYPE_INTERRUPT) and
(EP^.bEndpointAddress and LIBUSB_ENDPOINT_DIR_MASK <> 0) then
Based on looking at something similar in libusbutil... but I'm not sure it's
right at all.... I'm not sure if USB_ENDPOINT_TYPE_MASK was really changed to
LIBUSB_TRANSFER_TYPE_MASK or if something else happened. But at least it
compiles...
but now I've hit a few items that I just don't know what to do with. I can't
find anything similar to get a reference from:
libusboop.pas(1198,28) Error: Identifier not found "USB_TYPE_CLASS"
libusboop.pas(1199,5) Error: Identifier not found "USB_REQ_HID_SET_REPORT"
libusboop.pas(1216,27) Error: Identifier not found "USB_TYPE_CLASS"
libusboop.pas(1217,5) Error: Identifier not found "USB_REQ_HID_GET_REPORT"
libusboop.pas(1227,23) Error: Identifier not found "HID_REPORT_TYPE_OUTPUT"
I've tried things that seem to be in line with other changes, like changing
USB_Type_Class to LIBUSB_TYPE_CLASS or spelling out REQUEST instead of REQ
which also seems to be done in other places, but still the identifiers are not
found... the problem is I have no idea where these identifiers were/are defined.
I made a fork in github and a branch called "test" here:
https://github.com/Zaaphod/pas-libusb/tree/Test
Any advice is greatly appreciated
