I have a USB hub to attach to WGT634U with openwrt, revision is r12345, I want to attach more USB device on the router, but the hub seems not work, the hard disk could work when directly insert to route but unable be recoginzed via the USB hub, I think USB hub itself is good as I can use it in win xp.
dmesg output:

I could not found the disk by fdisk -l after boot.
Anythin I missed? or not support USB hub?

I had a WGT634U with a USB 2.0 HUB with HD, two printers and bluetooth running for about two years, until 2008/08 when I switched to an ALIX2C3.
Is the hub actively powered? Maybe one of your USB cable is faulty?

Bingo! The hub needs to be powered, especially for HDD or older USB Sticks. You need a hub with it's own power cord. The 5 volts over USB isn't enough for alot of devices.

actually I only have one device (HDD) connect to the HUB, I think power shoud from the WGT634U should be enough because I have hacked the router's hardware by combine the two way USB power to router's USB port, and I could use the HDD pretty well when it's directly plug into the router's USB port. I could also use the HUB plus HDD in WIN XP.

BTW The HUB did not have its own power cord.

Is this the hack you implemented on your WGT634U USB port?

Don't do too much thinking, test the hub with it's own power supply ;-)

Bingo! you got it

Don't know how... the HUB did not state it has external power plug, I did not found anywhere that I could insert a power plug... actually I never see any USB hub in local market has power supply...

If you are able to get your external HD working with an external USB power, then the Is hack isn't good. Can you confirm this?

Yeah, you are right, I supply the HD with external power supply, then it's working well with USB hub, seems its really a problem of weak current. Then whether it's helpful to supply the router with a more powerful AC/DC adapter?

The original AC/DC adapter for a Netgear WGT634U is ONLY rated @12VDC 1A. If you had done the mod to your WGT634U, I believe you will probably need to replace its original AC/DC adapter with a higher Amps throughput. Otherwise, the original AC/DC adapter will only be able to deliver up to 1A current even though the mod works.

So, I currently have a USB-audio dongle (C-Media) on my WGT634U, and it works with no problems.
If I want to add an external disk (which has its own power), I'll need a hub, which means that the WGT will be powering the hub and the audio, but not the disk.
My hope is that I can use a non-powered hub - any guesses?

(Sorry for reviving a slightly-old question)

whbjr,

I would guess that you could add a hub and a powered usb drive and plug in your audio without a problem.  Have you tested this yet?

This is off-topic, but you say that you have audio working with a C-media device.  This seems to be one of few recent reported instances of this working.  Can you say what you installed to get this working?  A listing of the output of "dmesg | tail" when you plug in the device would be great, and also a listing of lsmod.  If you don't want to post OT to this thread, could you please post at the relevant current thread:  http://forum.openwrt.org/viewtopic.php?id=20086

Thanks.

I'll answer over there... Thanks for the advice re. the hub, and for the link to that thread!
