Hello, how are you?
I am connecting two Global Shutter USB cameras for license plate capture and I get error when I try to read with both cameras. It tells me that there is no bandwidth.
I have also tried with the GPIO port with a powered HUB and nothing. Whenever it detects a USB 2.0 camera it puts it on the same bus. I need one of them to be on bus 002->khadas@Khadas@Khadas:~$ lsusb -t
/: Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd-meson/1p, 480M
|__ Port 001: Dev 002: Dev 002, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 001: Dev 003: Dev 003, If 0, Class=Video, Driver=uvcvideo, 480M
|__ Port 001: Dev 003: Dev 003, If 1, Class=Video, Driver=uvcvideo, 480M
|__ Port 004: Dev 004: Dev 004, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 004: Dev 005: Dev 005, If 0, Class=Video, Driver=uvcvideo, 480M
|__ Port 004: Dev 005, If 1, Class=Video, Driver=uvcvideo, 480M
/Bus 002.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd-meson/1p, 10000M
How can I make, or force one to run on Bus 001 and the other on Bus 002?
I have tried to modify the kernel options->
sudo nano /boot/extlinux/extlinux.conf
APPEND ${rootdev} ${bootargs} ${consoles} ${partitiontype} fan=$${fan_mode} ${boot_user_args} xhci_hcd.quirks=0x800000 usbcore.autosuspend=-1
And nothing…

Please, if you can help me.
Thank you very much in advance!
