Netgear R6220 USB Driver

Installing and Using OpenWrt
1

I'm trying to use a USB modem (Huawei E3372) on a Netgear R6220 with Lede (SNAPSHOT, r3904-c3778f2).

On my old OpenWrt the modem works without problems:

root@OpenWrt:~# dmesg|grep -i usb
[    4.440000] usbcore: registered new interface driver usbfs
[    4.440000] usbcore: registered new interface driver hub

[   15.240000] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB1

But with lede I only get:

root@LEDE:~# dmesg|grep -i usb
[    6.280000] usbcore: registered new interface driver usbfs
[    6.300000] usbcore: registered new interface driver hub

[   13.770000] usbcore: registered new interface driver qmi_wwan

cat /sys/kernel/debug/usb/devices is empty and lsusb says:

root@LEDE:~# lsusb
unable to initialize libusb: -99

Other posts mentioned that this means I'm missing an usb driver:

root@LEDE:~# lspci
00:00.0 PCI bridge: Device 0e8d:0801 (rev 01)
00:01.0 PCI bridge: Device 0e8d:0801 (rev 01)
01:00.0 Network controller: MEDIATEK Corp. MT7662E 802.11ac PCI Express Wireless Network Adapter
02:00.0 Network controller: MEDIATEK Corp. Device 7603

So far I installed the following:

opkg update && opkg install comgt kmod-usb-serial kmod-usb-serial-option kmod-usb-serial-wwan usb-modeswitch kmod-usb2 kmod-usb2-pci

I'm stuck. What driver do I need?

2 
opkg install kmod-usb3

got it working!

Thanks !
I had the same issue with the e8372 ( which worked in OpenWrt with only kmod-usb-net-cdc-ether package ). In LEDE I installed kmod-usb3 as you suggested and then needed kmod-usb-ohci apparently.

@laktak R6220 support in trunk already includes the kmod-usb3 package in its profile, so it should be built-in...

You're sure the kmod-usb3 package wasn't present already?

It was added after I submitted a bug report :``)

Oh boy am I late to the party :blush:
