Outdated version of usbdrv/usbdrv.c in your repository

[vobsch]

Thanks for sharing your work! I sucessfully implemented a HID keyboard on a ATtiny212.

Trying to implement avr-cdc on a ATtiny1614 I ran into problems: My Linux PC was unable to set DTR and RTS handshake signals. The reason: The file usbdrc/usbdrv.c you provided seems to be outdated, Pls. compare it to respecive file in v-usb repository on github or see following diff:

Thank you for the report. Can you please post a link or attachment to your modified usbdrv.c that you are using with V-USB_TinyAvr. www.github.com/v-usb/usbdrv/usbdrv.c results in "Not Found". Thank you.

Sorry, the correct URL of usbdrv.c is: https://github.com/obdev/v-usb/blob/master/usbdrv/usbdrv.c
