With usb delay-use, now my system freezes maybe 1 time out of 6, which is much better, but not awesome.

I know that grub2 does not have boot from CD options enabled--it's possible, I imagine, but it's not like it's setup. Besides, the freeze is happening within the kernel, for sure.

Well, maybe ...

lol turning acpi=off was very bad. It was pretty hairy loading that way and I don't think much loaded at all, in fact.

I'll keep acpi I guess. For the moment, I think the use_delay helps the kernel pass through the ACPI loading of the USB device, though I can't imagine why. So thanks!

Hi Josh,

Thanks for the thoughts!

Hmm, well, I do know that I'm getting the error in the initial booting of the kernel, during ACPI. I've tried turning ACPI off but I got the same error. Maybe I can try again:

Anyway, here's the output:

[ 0.256802] ACPI: Interpreter enabled
[ 0.256880] ACPI ...

Hi Josh,

I'm sorry to keep bringing up this blasted device. Aka the Cisco AM10.

I know you said you're not an expert in boot issues, but I can tell you that my system hangs when my Cisco AM10 is plugged in, and this is after I've chosen my Linux distribution on Grub 2.

I can tell you that it ...

Being a bonehead, my bad.

YES, it works! libusb-dev and restart and I was able to build the new version of usb_modeswitch and now my AM10 is working again. THANK YOU!

SORRY--below is my original post.

Just to make sure I'm not being an idiot, I haven't posted lsusb but I'm pretty sure this is ...

UPDATE: Sorry, I didn't realize there was a bug with 2.1.1. See the post below this one for an updated attempt to get it to work.

Sorry, let me give an update to the last post.

I just noticed this bug report in 2.1.1.

https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch

That said, I just ...

Version 2.1.1 or something like that ships out with Ubuntu 14.04, Linux Mint etc. But the Cisco AM10 has been working since version 1.9. In fact I see "cisco mode" with my precise lsusb output and it's not working.

Here are my two attempts to get it to work:

usb_modeswitch -v 1307 -p 1169 -W -L ...

Just a note to say that the Cisco AM10 is acting up out of the box on Ubuntu 14.04 and Linux Mint 17. That's really too bad since it was working out of the box on many systems... and in fact, it was working out of the box on the Linux Mint install CD!!! So I'm not sure what's going on when it's ...

ohmysql
ok then if you don't mind me asking. does it actually use the windows driver or the rt2800usb linux driver? if it uses the windows driver then it ain't ever going to work on this ARM device. it appears to be switching but it's not xmitting, the power level is zero.

I use the rt2800usb ...

I agree, I would now bring that question back to ubuntuforums.

lol! I'm open to recommendations on a new distro.

Good to know it may not be the AM10!

And yes, it just says "bite me."

I PMed you about your rant, I'd be curious to hear more.

It's most likely distribution dependant, and probably should be filed as a bug against Ubuntu.
(Ubuntu uses grub 2 by default, and the startup is tuned more towards making that nightmare mostly functional)

Does your system have similar issues if you have a random non-bootable USB stick plugged in ...

Ah, I have news!

I found out that actually my USB has problems not in GRUB but in the boot-up of Linux!

I know because when I ask linux to boot in text mode, I see a bunch of kernel messages and then my computer freezes about 1/6 times I boot up.

As a reminder, when I have the Cisco AM10 plugged ...

If you wait until Xorg/desktop is up, does it hang, or only while booting?

Only while booting. I can't even confirm that grub finishes because I get no text. And it's only every 6-7 boots that this happens. I can confirm that I the GRUB tone goes off - (because it's set to the inspector gadget ...
