armbian-config has significantly changed in Bookworm/Kernel 6.6. It looks to me that its not reflecting the actual device settings. Please refer to the attached screenshot from /boot/armbianEnv.txt. Compared to Bullseye/Kernel 6.1.92 I see an additional line "fdt_overlays, where all the dtb settings from the new armbian-config appear, fdt_overlays=sun50i-h5-analog-codec sun50i-h5-i2c1 sun50i-h5-tve sun50i-h5-uart2 sun50i-h5-usbhost0 sun50i-h5-usbhost1 sun50i-h5-usbhost2 sun50i-h5-usbhost3 but they seem to not having any effect. In 6.1.92 this line does not exist. The real dtb settings are still in the line above overlay_prefix=sun50i-h5 overlays=i2c1 uart1 usbhost0 usbhost1 usbhost2 usbhost3 which is identical in 6.1.92 and 6.6.

I configured my opi to work as a composite usb gadget (mouse and rndis). Everything works, but the actual refresh rate of the mouse was 250 Hz. I tried to configure bInterval, which is responsible for the device update frequency, this could only be done by rebuilding the kernel with bInterval changes in the high-speed descriptor structures from 4 to 1 in the file drivers/usb/gadget/function/f_hid.c. It had an effect. But the frequency only rose to 500 Hz. I tried to find what could limit this, I looked in drivers/usb/dwc2/gadget.c and also in composite.c but I couldn’t find anything. Now I don’t know where to look next or i missed sth.. drivers/usb/gadget/function/f_hid.c /* High-Speed Support */ static struct usb_endpoint_descriptor hidg_hs_in_ep_desc = { .bLength = USB_DT_ENDPOINT_SIZE, .bDescriptorType = USB_DT_ENDPOINT, .bEndpointAddress = USB_DIR_IN, .bmAttributes = USB_ENDPOINT_XFER_INT, /*.wMaxPacketSize = DYNAMIC */ .bInterval = 4, /* FIXME: Add this field in the <<< changed to 1 * HID gadget configuration? * (struct hidg_func_descriptor) */ }; static struct usb_endpoint_descriptor hidg_hs_out_ep_desc = { .bLength = USB_DT_ENDPOINT_SIZE, .bDescriptorType = USB_DT_ENDPOINT, .bEndpointAddress = USB_DIR_OUT, .bmAttributes = USB_ENDPOINT_XFER_INT, /*.wMaxPacketSize = DYNAMIC */ .bInterval = 4, /* FIXME: Add this field in the <<< changed to 1 * HID gadget configuration? * (struct hidg_func_descriptor) */ };
