I hope the following will illustrate my idea (it should just show the idea,
no deeper sense):
I assume a CPU with two USB device ports, e.g. ci_hdrc.0 and ci_hdrc.1.
On ci_hdrc.0 a gadget with serial console and network is configured, on
ci_hdrc.1 a CD-ROM and a camera.
config gadget gadget1
option manufacturer 'OpenWrt'
option product 'OpenWrt USB CDC/ACM'
option serial_number '007'
option usb_vid '0xbeef'
option usb_pid '0x1234'
option udc_dev 'ci_hdrc.0'
option disabled 0
config configuration config1
option gadget gadget1
option maxpower 120
config function console1
option gadget gadget1
option type 'acm'
option disabled 0
config function network1
option gadget gadget1
option type 'rndis'
option host_addr 00:01:02:04:05:06
option dev_addr 00:01:02:04:05:07
option disabled 0
config gadget gadget2
option manufacturer 'OpenWrt'
option product 'OpenWrt USB CDC/ACM'
option serial_number '007'
option usb_vid '0xbeef'
option usb_pid '0x1235'
option udc_dev 'ci_hdrc.1'
option disabled 0
config function msd
option gadget gadget2
option type 'mass_storage'
option file '/path/to/backing/file'
option removable 1
option cdrom 1
option disabled 0
config function network
option gadget gadget2
option type 'uvc'
option disabled 1
Cheers,
mhei
