The lsusb -t (as root) seems to give the needed results: gene@shop:~/linuxcnc/nc_files$ sudo lsusb -t /: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M |__ Port 2: Dev 2, If 0, Class=HID, Driver=usbhid, 1.5M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/8p, 480M |__ Port 4: Dev 2, If 0, Class='bInterfaceClass 0x0e not yet handled', Driver=uvcvideo, 480M |__ Port 4: Dev 2, If 1, Class='bInterfaceClass 0x0e not yet handled', Driver=uvcvideo, 480M I'd take a wild guess and say that camera actually needs a USB-3.0 port? An lsusb -v is very very verbose, many screens full of stuff from the camera as every register in it report about half a screen full of data, 32 registers for this & that. Confusing and I am glad emc-camview can sort it. > ----------------------------------------------------------------------- > ------- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT > Server from Actuate!
