Hello community

Using 15.05.1 OpenWRT. Need USB support please.
Trying to attach Huawei E1550 modem. Can't get ttyUSB*. May be I'm doing something wrong...

USB port driver used is UHCI (+EHCI). BUT only under UHCI lsusb worked (and these folders /dev/bus/usb/001 and /002 appear).

So, I HOPE, it's a real hub. dmesg as shown below:

# dmesg | grep USB
[   62.004572] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
[   62.085625] uhci_hcd: USB Universal Host Controller Interface driver
[   62.097815] uhci_hcd 0000:00:10.0: new USB bus registered, assigned bus number 1
[   62.121944] hub 1-0:1.0: USB hub found
[   62.146095] uhci_hcd 0000:00:10.1: new USB bus registered, assigned bus number 2
[   62.163373] hub 2-0:1.0: USB hub found

[   62.927700] usbserial: USB Serial support registered for IPWireless converter
[   62.946306] usbserial: USB Serial support registered for GSM modem (1-port)

# dmesg | grep usb
[   61.970515] usbcore: registered new interface driver usbfs
[   61.976295] usbcore: registered new interface driver hub
[   61.982087] usbcore: registered new device driver usb

[   62.940394] usbcore: registered new interface driver option
[   62.946306] usbserial: USB Serial support registered for GSM modem (1-port)

BUT
No USB device is recognized after it's plugged in. No 3g-modem, no flash-drive, nothing...
lsusb shows hubs only either BEFORE I plug the device, or AFTER.

root@OpenWrt:~# lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Can anyone advice anything?
TNX in advance!!

The "root hub" is part of the controller chip. That seems to be the only part that is working.

Which router model?

Some require a GPIO port to be set to turn on the 5 volt power output to the USB port. If your modem, etc. receives no power, it will not log on to the bus either. Try plugging a mobile phone into the USB and see if it charges.

RESOLVED

Power supply seems was an issue - I tried to use same Voltage, but less Amperage not native power adapter.

After I plugged native one - problem gone.

GUYS THANKS!!!!!!!!
