Greetings,
I'm having a problem when connecting my TyTN to my Thinkpad T43. When I connect the TyTN to a USB port (regardless of which one) on the laptop, it connects initially and starts charging, but after a while it disconnects, the charge light goes out and Windows puts up a message saying that the USB port has malfunctioned.
Unplugging and switching to a different USB port does not help, and I've tried a different USB cord without any change.
It seems a bit intermittent because right now as I'm writing this, it has stayed connected for quite a while.
I'm wondering if anyone else has experienced this problem - I'd like to try to figure out if it is a hardware problem with the TyTN, something specific to Vista, or a problem with the Thinkpad itself.
Maybe the TyTN is drawing too much power from the USB port while charging?

Hi I have a strange USB issue.
When I connect to my pc (win 7), the phone charging icon appears, but no red charging light. Also, after about 10 seconds, the phone stops charging.
It will charge on a mains charger no problem, and I can flash ROMs, task 29, etc - obviuosly via USB - with no problems. It just won't charge or sync with zune.
The same happens with another USB cable, and both cables charge and sync with zune on another phone running exact same ROM.
Anyone any ideas? I'm guessing its the micro usb port on the phone but its strange that I can still flash ROMs via USB but it won't charge or sync...
Peace
Ok, managed to solve this.
Looked in device manager and the phone was listed as "unknown device" with a yellow exclamation mark. I opened up the properties window, clicked on 'update driver' and lo and behold it installed a USB composite device driver and it now charges and syncs just fine ....
Hi, I have Bowers & Wilkins USB speakers, which works fine in Windows 8, including remote control of the applications, but what they do not survive unplug and plug operation. I am using them with my Lenovo T400s notebook, and after I plug them again, the Windows 8 says, that the USB device was not recognized. After restart its OK. I have found as well, that if I plug them while they are turned off and then turn them on, that this problem occurs. But if I plug them turned on, it seems, that it usually works fine. Anybody has similar problem with USB speakers? I am using Windows 8 With Media Center Release Preview Build 8400.
Last night I updated to 4.3 via the very useful thread here, http://forum.xda-developers.com/showthread.php?t=2145848
I was in situation "A" with a completely stock Nexus 4 and the side load went without a hitch. I was able to charge my phone from my wall charger last night with no issue. Today at work I realized that my phone was not charging from my PC via USB cable like it usually does. If I disconnected and reconnected I would see "Charging" on the Battery page for a split second then it would change to "Not Charging" and the phone would notify me that I was connected as a media device.
Trying to troubleshoot the problem I had rebooted the phone and the PC, no luck. I tried turning off the check box that set the phone as a media device and when I unplugged and replugged in my phone it started charging again. To test my theory I turned the "media device" option back on and charging stopped right away. Has anyone else seen this?
Steps to duplicate:
1) Connect phone to PC via USB with Connect as "Media device (MTP)" checked (Settings -> Storage -> Menu -> USB computer connection)
2) See that the phone is not charging.
3) Uncheck "Media device (MTP)"
4) Unplug and replug in USB cable
5) See that the phone is now charging.
6) Re-check "Media device (MTP)"
7) See that phone immediately stops charging.
Not sure if this matters but the PC is running Windows XP. Up until today I have had no issues charging and nothing has changed configuration wise on the PC that I know of.
Thanks,
Eric
A friend of mine just had the problem. It seems that, since 4.3, you can no longer charge if MTP or PTP is activated AND your peripheral is not recognized by the system. I mean, since it is work computers, I assume you do not have privileges to install drivers for your phone. And so, it won't charge until you deactivate the MTP fonction. At home, where your phone is properly recognized and drivers are installed, no problem.
Another solution is to find a "charge only" usb cable, like the ones delivered with external batteries for example. We tried it, and it works also even without deactivate MTP or PTP.
Same Issue. On two different devices out of the box.

I own two Samsung devices and they both have the same issue. I have tried different power cords, different USB 2.0/3.0 slots on a Linux laptop, Windows laptop, Mac Mini and Rasperry Pi, turned on developer mode to no avail. The few things I do see that both devices when plugged into an outlet they say Charging (AC). Once unplugged and plugged into a USB port the nav title bar hides and comes back with the battery icon with a red X and stating discharging. I have yet to find a fix for either.
- Samsung Galaxy Tab 3 10.1" 2013 GT-P5210ZWYXAR 4.2.2 Build JDQ39.P5210OUEAMK1
- Samsung Galaxy Note 8 8.0" 2013 GT-N5110ZWYXAR 4.1.2 Build JZ054k.N5110OUEEMF2
Not a fix. Just a possiable answer.

Android 4.4.4 CM 11S USB Charging Issue Resolved
Hi,
I had the same problem with my OPO. My previous device was JellyBean and I could charge even when it was connected as Mass Storage.
My new device used to connect as MTP by default and hence would not charge. I charge it from my work PC which has blocked media transfer through USB and that was the real problem. When I uncheck MTP and connect my device, it would charge. Since my Home PC has no such settings there is no problem when I connect it to that.
Guys I'm trying to connect my phone to laptop but phone doens't get recognised in the laptop. The device makes sound and so does the laptop. No pop-ups in either of devices. The phone starts to charge but no option in the notification shade to change the mode of connection though. I've tried with turning on the usb debugging too, but no help.
Laptop pups up an error message later that the "LAST USB DEVICE YOU CONNECTED MALFUNCTIONED. WINDOWS DOES NOT RECOGNISE IT".
Is this falut of my charging port or of laptop? Or windows 10?
I've tried connecting to all other ports and with different cables. My all other android devices connect though. Please help.

I've had this issue with pen drives and my USB port had an issue(short circuited).
Check these :
Try running devices troubleshooter from control panel.
If the phone is charging properly by using the same cable , it's probably an issue with the laptop.
Is it on pie?

1. Enable USB Debugging in developer options
2. Download and install ASUS USB Driver from asus website like below. Search for ASUS_Android_USB_drivers_for_Windows

Sir I've tried debugging thing already and set the option to MTP. I've run troubleshooter too but windows couldn't identify and solve the problem. I'm guessing the problem is with windows 10. So I've decided to installed windows 7 in a different drive. Maybe that'll solve the problem.
Phone is running on Oreo.
Note:- I think micro usb has four pins. One among them might be a ground pin. One must be for charging and other must be to transfer data. Correct me if I'm wrong.
I had several times repairing phone with broken micro usb connector, it has 5 pin to be soldering on it. 2 for the power and 3 for data transfer. If the cable is fine for other devices then maybe the problem is not from the cable itself. I had an experience like that case before that if the notification from the pc says connected device is malfunctioned, that may caused by when u first time connected the phone to the pc, the device is disconnected when it still trying to instal the driver. When u connected the phone to pc check on the device manager, if u see "!" icon there, then theres the problem, ur phone driver not installed properly, u can try manual instal of device driver from there.
Last usb device you connected malfunctioned. Windows does not recognise it
"USB device not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it” always appears in Windows 10 and Windows 8.
And the reasons for the issue contains:
The currently loaded USB driver has become corrupted or unstable
USB drivers need to be updated
USB drive may be entering selective suspend
USB has some damaged files or bad sectors
USB drive has not been formatted correctly
For different reasons, you need to take different measure, but you can directly format it via AOMEI Partition Assistant to solve the usb device not recognize issue.
The USB port itself was damaged. So I got replacement and now the new phone works fine with same laptop. Thanks you all for your replies.
