Hi Paul,
could you please take a look at usb_dec.h?
I think the config for USB_MTPDISK_SERIAL is wrong. My Lubuntu (dmesg) says:
Code:
[ 58.300446] usb 1-1: new high-speed USB device number 2 using ehci-pci
[ 58.659302] usb 1-1: config 1 has an invalid interface number: 3 but max is 2

If have modified it to :
Code:

#define PRODUCT_ID 0x0476 //fake an include everything device
#define RAWHID_USAGE_PAGE 0xFFAB // recommended: 0xFF00 to 0xFFFF

#define MTP_EVENT_SIZE 32
#define MTP_EVENT_INTERVAL_12 10 // 10 = 10 ms

#define ENDPOINT4_CONFIG ENDPOINT_RECEIVE_BULK + ENDPOINT_TRANSMIT_BULK
#define ENDPOINT5_CONFIG ENDPOINT_RECEIVE_INTERRUPT + ENDPOINT_TRANSMIT_INTERRUPT // ????
Now, Linux seems to be happy, but I'm not entirly sure, that it is correct now.
Thank you!
Edit: After a while, it continous to write:
Code:
cdc_acm 1-1:1.1: failed to set dtr/rts
Not sure, if this is normal.
Then, lsusb needs a long time (several seconds) to display the verbose info for the Teensy (tested with USB_MTPDISK_SERIAL only) and sometimes fails to prints the strings (serial-no, manufacturer etc)
