TMK USB to USB keyboard converter
pupmonster:
Thanks, Hasu!
I thought you would like to know that I used the TMK Layout Editor to modify my layout of the Japanese Mini M using both my older USB-USB adapter and the brand-new adapter just received, and everything looks good.

Hi,
so does this work if there is a hub between the real keyboard and the converter? Is it possible to have the firmware supporting for mouse only? (We have a devices that accepts only keyboard or mouse directly attached, but we need to use a USB over LAN that shows up as hub between keyboard / mouse and the device? Need tens of units.
hasu:
- My firmware with current configuration can support two hubs. Yes, you can use hub between the converter and keyboard.
- My firmware does not support mouse.
It is possible for the converter to support hub, keyboard and mouse technically if you can write custom code for that.

Hi Hasu,
I received my usb-usb converter the other day (thanks!), and I've been partly successful using it with my Chilkey ND75. Everything is good if I use the USB cable connection, however I'm not able to get it working with the 2.4G wireless dongle.
I was hoping that if I post the debug & dump hid_listen logs that you might be able to help?

Many thanks,

Hi Tim,
Thanks for the info.
It seems interface0 is boot keyboard compatible but it does not assert itself as a 'Boot keyboard' in USB descriptor for some reason. So Chilkey ND75 dongle is not a boot keyboard and the converter cannot detect it.
I'll look into to find a workaround for the dongle.
