USB 551L problems

I recently upgraded from a USB760 to a 4g USB 551L modem. At start up I always get a sim card error message. I remove the device from my laptop, remove the sim card then reinsert it. I hit detect device in the VZAM. When configuration is complete I can then connect to the internet. Once I have access, the device powers off and connection is lost. It is as if the device was unplugged then plugged back in. I wait for VZAM to detect signal again and then I can reconnect to the internet. This goes on for at least 4 to 5 time per hour. My USB760 never did this. If this is supposed to be some sort improvement, I'm not seeing it. Anybody have any suggestions.

I can definitely see how this can be frustrating for you. I have had connection issues with my USB modem as well.
In regards to your trouble shooting steps, have you tried to uninstall and reinstall VZ Access manager? Have you tried using the USB 551L modem on another computer? Do you have any anti-virus programs running? If so can you disable them and try to connect again?
Here is the link to download the latest version of VZ Access Manager.
I hoped this helps.
Thanks.

Usb 551L disconnect problems

I just "upgraded" from the 3g modem to the 4g (551L). The 3g worked great for all my internet needs. The 4g kicks me off every few minutes, especially (it seems, though I'm still new to it) when I'm skyping or other high bandwidth. It doesn't give any notification of kicking me off; it actually still says "connected" but all my internet services stop working.
I have the newest access manager on 3 differnent Macs (10.4.11, and 10.6.) and it's the same on all. It's horrible. I want my 3g back (i'm not in a 4g service area). Ideas?

Hello Kipchoge,
I would like to make sure that your USB modem is functioning as it should. On 11/14 we released a major software update for the USB 551L that addressed the concerns your are having with the connectivity. Here is a link that describes the update and the installation instructions. Please let me know if I can troubleshoot further as I would be happy to address any lasting concerns. I look forward to hearing from you.

USB Sound Problem

I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.

They are plug and play.
I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything?

Lumia 620 usb disconnection problem

Hi. Am facing a problem of usb disconnection while transferring data from my laptop. It's good for 1 or 2 minutes, after that am getting device not available on my laptop.
Also I noticed the charging symbol on battery is blinking when connected to usb, but ok when connected to power cord. Is that blinking normal?
clarify please

The blinking is not normal. I haven't run across any bad USB cable problems on Nokia phones but there have been some HTC USB cables that work to charge but not fot the PC connection. If you have another similar USB cable try it. Try other PC usb ports also

After upgrade to ios 6 usb connection problems with car stereo

Hi Everyone,

I am sure, that the upgrade ist the culprit; worked fine before. My car stereo is built in a Volvo XC 60; the device is connected via the standard usb cable by apple.
Any Ideas?

[N85] USB charging problem

Hello all,
I tried to charge my N85 with an [non-Nokia] USB battery charger (Lenovo 90W Slim AC/DC Combo Adapter) via the Nokia Connectivity Cable (CA-101) to keep down the amount of chargers I have to carry.
But except of asking, which data connection profile I want to use, there is no charging at all.
Am I doing something wrong or is the N85 only chargeable by the original Nokia wall charger?
Thank you
sicut

@sapporaby: Are you sure you have read my post completely? "Apple" is a brand o usb charger that does not work with my Nokia N85. It's a brand like "Kensington", with a usb charger that do work. Both usb charger worked with my old Nokia N95. I just want to know whether someone else has this problem usb charging problems too or if only my problem, and to make know @sicut that he is not the only one with usb charging problems with his Nokia N85 and his Lenovo charger.
@sapporaby, is it "apple" a word taboo for you? Why "kensington" is not taboo? Why "lenovo" is not taboo either?
1. I have had every Mac made since 2003.
2. I am typing this on a Mac now.
3. I have had and still have every iPhone made.
4. Same with every brand iPod.
5. I am running Apple software right now and the Nokia for Mac software.
Is that taboo enough for you? DON'T ASSUME because now your taboo question is moot.
As for your the Apple charger does not work issue, my question still stands. While your Apple charger may have worked with your N95 there is no reason why it should work with your N85. Are they the same phone?. Is the N85 made by Apple? No again. Does the Apple charger supply the same charging voltage as the Nokia charger that came with the phone? These are issues that come into play. What is so hard to use the cable that came with the phone. It seems, and maybe I am wrong but you and the OP are making a mountain out of a moe-hill.
Just use the cable that came with the phone, in the USB port of your computer and be done with it. I am having a very hard time trying to understand what the problem is with using the cable.

N78 USB CONNECTIVITY PROBLEMS

Hy guys,
Since i've bought my N78 i've been able to connect the phone via cable only one time. After that, every time i've tryed to connect my n78 via cable my computer doesn't recognize my Phone.
When I plug USB cable in one of the USB ports, Windows XP gives me back an error that says "USB devices not recognized - One or more devices connected to the computer has not worked correctly. Windows is not able to recognize it".
I've reinstalled PC suite thousands of times,but nothing changes.
My phone has the 12.046 software version. I know that there'e a newer version but how I can update it if my PC does not recognize the phone, and hence, PC suite is not able to connect to the phone.
Many thanks for you help
m

you have another option in updating via Firmware Over The Air. you can do this by entering *#0000# in the standby screen and selecting Options > Check for updates. if an update is not available over NSU, then it may be on FOTA instead for your product code. this method of updating only takes about three to five minutes anyway. remember to do a hard reset (three-finger hard reset) after updating your phone to the new firmware.
so you can probably update from 12.046 to 20.149 or 21.002. USB connectivity problems are probably due to problems with the USB cable or the computer, i have had no problems at all with USB connectivity in all the time i've had my N78, even under 12.046 firmware.
let us know how it goes.
If you found this or someone's comments helpful or like what that person has to say, please give some Kudos to their post!

USB 551L wont update firmware correctly. VZW tech plz help!

Ok, so when i go to update my usb 551l, this is what occurs, http://i1111.photobucket.com/albums/h461/Terry_Horgan/Capture-20.png
I have tried everything, my device is not updated to the current firmware, and this program will not open to do it either. Please help get this fixed. It should update it, I have done it before on a different computer, right after a fresh restore.
PLEASE!

My 551L connection reliability was so bad I could not complete the firmware download so I took it to my local Verizon phone store. They did the latest (1.48 4/30/2012) upgrade. Do not expect any improvements. This thing remains an unstable piece of junk regardless of the firmware version.

USB mounting problem

I have done my best to research this, but have not found a solution.
After a new Arch installation on a new machine (Dell Precision T3400) I am unable to change the permissions (even as root!) on files once they are transferred to the usbstick (a Code 1 error message is returned). Other operations, such as copying, moving and deleting occur as usual. I have also noticed that as soon as files are transferred to the USB stick, the permissions get changed (but not the ownership), as if whatever is reading the stick is also changing the permissions.
It is not the stick -- the same stick performs normally on every other computer I use it on.
fstab: /dev/sdc1 /mnt/usbstick vfat rw,user,auto,sync 0 0
(basically the same as on 3 other Linux machines I use, all running Arch).
When mounted, sdc1 has ownership root:disk. I have added myself to the disk group. /mnt/usbstick has myself as the owner.
Not a major problem, just slightly irritating.
Thea

Thanks, Pheon --
I just noticed I made a mistake in giving my fstab line, it should be:
/dev/sdc1 /mnt/usbstick vfat rw,user,noauto,sync 0 0
(so "noauto" instead of "auto" in the mount options)
As I indicated, this is not a USB stick problem (same stick works just fine on other machines) -- also, in my attempts to troubleshoot this, I changed the filesystem on the USB stick to VFAT -- previously, it was whatever the default is when it comes out of the factory, and at that time the fstab line looked like:
/dev/sdc1 /mnt/usbstick auto rw,user,noauto,sync 0 0
Same situation, i.e. changing the filesystem did not affect the problem in any way.
Any other ideas?

Usb ipod problems

It recognized the new iPod as "Unknown Device" in Device Manager... I went through all the steps I found in the Apple support network - and to no avail...
There's always that unrecognized yellow exclamation point on the question mark icon, even though the iPod is charging fine... What to do?
Thank you in advance
Ran Bleich

I have exactly the same problem, my 4g 20 gb Ipod will report a fully charged battery when I connect it to the Apple USB AC adapter (or any other AC USB power adapter), connecting it to my Laptop USB 2.0 port gives the same indication, however, the battery is not really charged, upon disconnecting the cable from the AC adapter or the USB port, the battery icon reverts to its former status (almost completely discharged). The only way I can charge this Ipod is to connect it to a powered Firewire port or dock the Ipod in my Altec Lansing InMotion speakers, I know the USB AC charger used to work before I updated Ipod with the latest updater, I did the update just after it became available, I am not sure if this problem was caused by the update or not, I don't usually have to use the USB ac adapter, so I can't tell if the usb charging problem appeared right after the update or much later.
It would be much appreciated if somebody posts a solution for this...

K8N Neo2 USB boot problem

Hi, I'm trying to fix my computer (it freezes on every operating system all of a sudden), and I need to use the USB boot to load Linux Live and Windows installation (both froze as well). The problem is that it'll take the USB just once in a while, and that is causing me a big loss of time to make the tests and a headache. First thing I did was memtest and I found corrupt memory, thus I replaced the DIMM. But the freezing is still there.
Do you have any hint? I know it's a double question but at least if the USB boot was working all the time it'd be a lot faster to load stuff and try to fix the problem.
Thanks for your hints!

First thing tell us what the rest of the PC consists of.
I didn't think the rest of my hardware would matter with the USB boot problem, anyway:
1.D BIOS
Athlon 64 3000+
512 mb ddr PC3200
Geforce4 MX 440 AGP
300W power supply
Maxtor 250 GB IDE
Thanks for your attention.

R835 P56X USB 3 problems

I have my R835 running nice now with Crucial M4 SSD, 8 gigs ram, 6230 wifi and the latest Bios & drivers. But, whenever I use the usb3 port to transfer files from or to my usb3 supported external drive, it starts out fast but then comes to a screaching halt at quarter or third into the transfer! The computer doesn't freeze or crash, its just like the port locks up! Then I'd have to use the other usb2 ports without any problems, but slower!
Any ideas? I made sure the usb3 driver is installed!
Thanks.

Check out this post from another forum:

USB 3.0 problem appeared on my Satellite R830 after a month of everyday use. Controller started to power itself off not only on heavy file transfers, but sometimes even with simple USB mouse connected to it. Problem existed on both OSes which I have installed on my SSD: 32-bit WinXP Pro with latest driver from Toshiba's website ver. 2.0.34.1 and 64-bit FC16 Linux with 3.1.2 kernel (i've swapped stock HDD to Intel 320 SSD and said goodbye to Win7).
After a small research it seems that this is not Toshiba's problem, but a bug in old firmware of Renesas uPD720200 USB 3.0 controllers. It is described here for example. I've installed latest Renesas firmware (4.0.1.5) and latest Windows driver (2.1.28.0) found here, and it helped. I think problem has completely vanished now on all OSes, so solution was in firmware update, not in driver.
