RC5+ compatibility

[ik8vrq]

Hi,

it seems to me that the new RC5+ device from Elitech is not backward compatible with RC5.
It shows itself as a hidraw device (ad as mass storage device as well) and not like a ttyUSBn serial port anymore.

Any chance for a new version able to exchange data with this device?

Regards.

Angelo

Hello, would a pcapng capture file from an RC-5+ device help you developing this feature?

[ulikoehler]

If that would help, I could also provide packet capture etc for RC-5+.

Could you describe the reason for the lack of support? I have (mistakenly, I guess) bought an RC5+ and am happy to help with implementation. What is needed?

The RC-5+ no longer uses a USB serial port, rather implements the USB HID interface class for issuing commands/receiving reports. Communication is now more complicated compared to RC-4/5 devices. Here is an example of the USB HID interface I see when plugging in my RC-5+ device:

          ===>HID Descriptor<===
bLength:                           0x09
bDescriptorType:                   0x21
bcdHID:                          0x0111
bCountryCode:                      0x21
bNumDescriptors:                   0x01
bDescriptorType:                   0x22 (Report Descriptor)
wDescriptorLength:               0x001B

          ===>Endpoint Descriptor<===
bLength:                           0x07
bDescriptorType:                   0x05
bEndpointAddress:                  0x82  -> Direction: IN - EndpointID: 2
bmAttributes:                      0x03  -> Interrupt Transfer Type
wMaxPacketSize:                  0x0040 = 0x40 bytes
bInterval:                         0x01

          ===>Endpoint Descriptor<===
bLength:                           0x07
bDescriptorType:                   0x05
bEndpointAddress:                  0x02  -> Direction: OUT - EndpointID: 2
bmAttributes:                      0x03  -> Interrupt Transfer Type
wMaxPacketSize:                  0x0040 = 0x40 bytes
bInterval:                         0x01

Hello, I also happen to have got an Elitech RC-5+ device and I developed a python client library with a command line interface to interact with is. The project python-elitech is very new, but I have already been able to reconfigure my data logger and extract the recorded data directly from the device memory. You are welcome if you want to give it a try!
Hope you will enjoy it!

Fantastic looking repo @pasccom, seriously impressive.

nb. I'm re-teaching myself Ansi C and have bought an RC-5+ device as a good starting point for a cross-platform, development project. Your repo is going to really help me get started as it will avoid the need for reverse engineering the messages/data structures.
