I have a dual RS232 adapter using a FT2232D [edit: corrected from FT2232C] chipset:

It works when connected directly to the WRT160NL but fails when connected via a 4-port powered USB 2 hub with the error:

root@OpenWrt:/# usb 1-1.3: new full speed USB device using ar71xx-ehci and address 11
usb 1-1.3: unable to read config index 0 descriptor/start: -145
usb 1-1.3: chopping to 0 config(s)
usb 1-1.3: string descriptor 0 read error: -145
usb 1-1.3: no configuration chosen from 0 choices

Detailed error outputs below.

Disconnecting from USB 2 hub:

usb 1-1.3: USB disconnect, address 11

root@OpenWrt:/# lsusb
^C
^C^C^C

(lsusb seems to crash the console after the serial adapter is disconnected from the hub.)

I realise this is bleeding edge at the moment, but the USB seems stable in all other configurations (I can connect a Hauwei E160 USB dongle and a PL2303-based serial adapter to this powered hub without problems). I was wondering if anyone else has come across a similar error.

I haven't made any progress on this issue unfortunately; after googling for 'unable to read config index 0 descriptor/start' it seems the usual workaround is to roll back to USB1.1, but neither kmod-usb-uhci or kmod-usb-ohci seem to work (for each: install, reboot, lsusb gives no output). I've not been able to determine whether this is a bleeding edge issue or something more fundamental.

Have you tried any other serial adapters, preferably other FTDI chipset products? Have you tried another hub? What model/brand device is the one you have?

I'm about to do some experimenting with a single port adapter, if I get it working I'll put a hub in the middle and test that.

A search of threads here found a few hub issues in older builds that were generally solved by updating to a more recent Kamikaze build, but your build is fairly recent, so that may not be the issue here...

Thanks, Jim. (Sorry, forgot to subscribe to this topic and missed your reply until now)

A mistake I made is that the chipset is actually the FT2232D, which acts as a 'full speed device' (12MBit/s) - slower than a 'high speed device' (go figure!) under USB2.0. I don't know if that's significant, but I was unable to find any other 'full speed' devices to test through the hub.

The hub is a Starforce Industrial 4-Port USB 2.0 hub which is running with a 24VDC supply.

I tried another USB 2.0 hub (unpowered) with an identical error - I'll get the details of that when I find it!

As for other USB-serial adapters, I currently have 2 ATEN UC-232A USB-serial adapters (PL2303 chipset) connected to the hub which are working. I'll have a hunt around to see if I have any FTDI-based ones.

Nice hub, I ordered an extremely similar one just a few days ago. Actually, when I was asking what model, I meant the serial interface, not the hub. Looks like I phrased that badly, sorry.

So, getting back to the rs232 interface, the fact that you have other adapters that work seems to point to this particular device just not liking being used with a hub. Do you have a PC/Mac/etc that you can try this box on with and without a hub?

Looking at your lsusb output above, for the test with a hub, I can see that it is detecting the hub, but I can't see that it is detecting anything plugged into the hub. Just for fun, if you have support added for USB storage, try plugging a flash drive into the hub and see if that is detected.

Interesting coincidence! The hub seems pretty solid, no complaints.

The serial device is a USB-2COM-M , it works through the hub when connected to a Windows XP box (laptop with Intel 82801G USB controller); my linux box is currently down with a failed PSU so I haven't tested it on that.

Other devices are working fine with the WRT160NL and the powered hub, just not the USB-2COM-M; here's the output of lsusb -vvv with two UTEN UC-232A usb-serial adapters and a Huawei E169 dongle connected:

Well, I'm out of ideas of things to check for, on the surface it seems like this should work fine, I keep coming back to some driver incompatibility within OpenWRT that is causing an issue here. Unless anyone else has another idea, I'd write up a bug on this and see where that leads.

FTDI is normally a pretty good chipset for serial, your other serial adapter is a 1.1 spec and not 2.0, but that shouldn't be a problem. Someone that knows more than me about these drivers is going to have to take the next stab at troubleshooting this one...

Hi there.
I was experiencing the EXACT same problem on the same router (160nl).
I used 4 ports usb 2.0 hub and I wanted to connect couple of BT dongles. the dongle worked fine when connected directly to the usb port on the router but I've got reading error for each and every BT dongle device connected to the hub, No matter if the hub was self powered at the moment or not.

this is the output of lsusb (as you can see it recognise the two BT dongles and the 4 ports hub):

root@OpenWrt:/# lsusb
Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and the dmesg output is:

usb 1-1.2: unable to read config index 0 descriptor/start: -145
usb 1-1.2: chopping to 0 config(s)
ar71xx-wdt: enabling watchdog timer
usb 1-1.2: string descriptor 0 read error: -145
usb 1-1.2: no configuration chosen from 0 choices
usb 1-1.3: new full speed USB device using ar71xx-ehci and address 4
usb 1-1.3: unable to read config index 0 descriptor/start: -145
usb 1-1.3: chopping to 0 config(s)

when trying to connect a usb flash drive through the hub, it worked fine, as you can see in the lsusb here:

root@OpenWrt:/# lsusb
Bus 001 Device 003: ID 0930:6533 Toshiba Corp. 512M Stick
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and the dmesg:

usb 1-1.1: new high speed USB device using ar71xx-ehci and address 3
usb 1-1.1: configuration #1 chosen from 1 choice

this whole setup worked just fine on my hp laptop running ubuntu 9.10:

[10015.860562] usb 2-2.2: new full speed USB device using ehci_hcd and address 13
[10016.029816] usb 2-2.2: configuration #1 chosen from 1 choice

Someone has any new Ideas about the problem?!

I'm afraid I haven't; I just reboot the device once I've finished using the serial port.

The issue stopped in later releases of OpenWRT, although I can't remember when and no longer have the hardware needed to reproduce the error. I'd suggest creating a new post and give the same details as I gave in this post.

The discussion might have continued from here.
