USB Mount

Not sure what fixed it, but the CM on G1 allowed me to mount my SD using my car stereo's USB (JVC KW-AVX820). Native G1 and none of the 3 USB modes on the Vibrant work. Any idea what file system feature did that?
Reuven

Same here. My Genesis Coupe keeps showing either 'Media Connection Error' or 'No Media Connected'. It even rebooted my nav/stereo this morning and then froze it on the FM screen with no audio. Had to turn the car off, then back on for it to be fine. Not sure why the Vibrant would have issues like that.
Actually, with my G1, I hadn't got USB Mount notifications for awhile. Other rom's however worked fine. My wife's MyTouch works no problem, so I know it shouldn't be the car.

I don't know anything about car computer usb, but I'll share one experience I had working with a copier at work: USB running in a mode that simulates a USB thumb drive works. USB running in a mode that shows a micro SD card READER (as opposed to a single solid-state unremoveable drive) does not. That discrepancy could be responsible for what you are experiencing.

Make sure after you select mass storage you then mount the usb (its a two step process)
But also, it still might fail as I've noticed when you do this the device is actually mounted as well (oh that glorious 16gb of onboard space!) so the stereo might not have any idea of where it should be looking.

You need to go into settings and enable USB debugging
I think it's under settings application development

that didn't do it

Try disabling USB tethering

W7 PC won't see rooted NC anymore

I rooted my NC from 1.1.0 using autonooter awhile ago and it works pretty well in general. I used to be able to hook it up to my home PC (w7) and my work PC (XP) with no problems. ADB worked (usually), the drives showed up, etc.
Everything still works on the work PC, and another W7 PC I tried it on.
Now, for some reason, neither the NC nor its SD card show up on my home PC when I plug it in! The NC shows the normal "USB Mode" screen when I plug it in, and my PC makes the USB Ding sound. But no new drives show up.
The only thing I can think of that changed is around the time it stopped working, I replaced my old USB Card reader with a new one (old one didn't work with SDHC). I also renamed some drive letters to reorganize them, since the card reader always shows 4 drive letters in windows.
I don't see the USB controller entry for the NC that I used to see in Device Manager either.

Check for NookcolorUMS app

I was having some bizarre connection issues with my PC, too, and they seem to have been corrected (at least they haven't recurred) by using a USB extension cable. It makes no sense, and I didn't do it to attempt a fix, but just noticed that the issues seemed worst when plugging into the top-side 'convenience' USB ports, and had an extra extension cable sitting around, so I plugged that into a rear port to make access less awkward. Since then, the PC consistently mounts everything just like it should.
I'm still using the NC's data cable, just plugging it into a maybe 1' extension cable rather than directly in the slot.

my XP based computer won't see the rooted NC either, however I will have to try using a port on the motherboard as opposed to one of the front mounts and see if that does the trick. I just kinda gave up on it as I didn't really need it too bad (I only use my nook for email, web browsing, and to control my DVR).

Well I unrooted my NC as I had planned anyway to upgrade to 1.2, but the problem hasn't gone away.
I tried plugging into an extension cable I have that goes directly to a MoBo rear port, but no change.
I can't run the nookcolorUMS now that I'm unrooted. Maybe I'll try it when I re-root eventually.
The thing is, it works on every other computer, so I can't figure out why it would stop working on just this one. It seems like it must be a windows issue, but I'll be damned if I can figure out what it is.

I don't bother with usb
USB connectivity is so unreliable that I don't even bother with it.
To move files around I use File Expert/network to access the PC via wireless from the device.
It's easy, reliable, and FAST.

That's a good tip. Unfortunately you have to use USB for certain functions, like manual nooting, or synching with Calibre (I suspect).
Once I'm rooted again I'll probably start using wireless for small stuff, but if I'm moving a gigabyte movie over, I'm not sure how long that will take, or how much battery it will use.

Does anything come up in device manager when you connect it? If so, did you try deleting anything that does come up, disconnect and start over? Worth a shot....

You don't have to guess--if you see a USB device that might be the NC, open properties>details and from the dropdown choose "hardware ids." If the number 2080 is in the id, it's the NC.

Nothing new comes up in device manager when I plug it in. It used to...

I experienced a similar issue and this was what causing it.
1. I have 2 front USB connections (nothing connected to either)
2. External Power USB hub connected to a rear USB slot
On Win 7, whenever I plug-in the NC via USB, I got a device not recognize error. I tried plugging it into different ports and pretty much either got no detection or device not recognize. Here is the kicker, as soon as I plug it into the usb hub, window recognize and mount it right away. This also happen to be true if I remove the usb hub altogether.

[Q] Question about mounting external Hard drives

Would connecting the external hard drive through the micro usb make a difference? Just wondering because i can't get my Iconia to read my external through the regular usb input. Already rooted and downloaded drive mount still nothing. Anyone's help would be greatly appreciated

shut the tab down and connect drive and then boot. Now try the drive mount, what exact steps did you take with drive mount.

Went ahead and shut down my iconia hooked up the external. Now, when i turn it back on i unlock it of course, once all the icons load etc.. the screen will go completely blank then the device will restart. Then it gets stuck at the android screen. I bought a 2tb western digital wonder if there is an issue with the external or something.

I don't know about a 2tb drive,might google that. I would remove busybox and drive mount and reinstall and try again. Im running honney villian and its latest kernal. I use on 1tb ntfs drive with no problems. Guess keep trying and reading, as it does work. Hope you get it going. What are you running

The Micro-USB port doesn't support external USB storage.
How are you powering the HD? If it's taking its power solely from the USB port, then odds are the tablet isn't providing enough juice. Try an external PSU on it, or use a powered HUB.

[Q] Play movies from nexus 4 on PC

Hi
Can I play movies on PC from nexus 4 while it's connected with USB cable like it was a regular flash drive?
When I try doing it the file is being downloaded first then plays. If the file is big it takes a lot of time.
I'm using windows 8.

Better copy the film to your pc first. I got the same problem but dont think this is os related. Just a bad read speed, worse than actually usb 2.0.

The speed is onpair with usb 2.0, still copying the whole movie to some unknown place instead of direct play is unnecessary and waste of time.
My previous phone had an sdcard which appeared as hard drive when connected to PC, but N4 appears as portable device. This sucks

That's because the Nexus 4 doesn't support USB On The Go. Search xda for "Nexus 4 OTG" and you'll come across some threads about this, and a couple of workarounds that might, or might not work for you :fingers-crossed:.

Hey there
I wasn't looking for USB OTG, which is a way to connect external drives to the device. I'm looking for a way to use N4 itself as a regular external drive while connected to PC. Currently it's seen by PC as a portable device and it's pretty limited.

I would assume increasing the SD read-ahead (if you're on a custom kernel) might help with your issue here. But as someone else previously mentioned, copying to PC is definitely the better option. That, or just enjoy the movie on your Nexus4

[Q] No Luck with Mounting Storage...help

Hi, I complained about the device having no UMS so one of the people told
me to root my phone and download Multi Mount SD-Card. I did that last night but I just can't get it to work. When I plug my phone USB into the my PC, sometimes it shows up as Removeable E for a bit but when I click on it, it tells me to insert disk.Do I need an OTG cable?
The whole reason I want this is that my Ford Sync Stereo system in the car needs to see the device as Mass Storage to access it properly to play music files. Some people have told me to use bluetooth and yes it plays the files but I can;t play by vouice command unless it is USB and sees the device as a mass storage device (drive).
Any help would be great please.
Thnx Dane
