As of this morning I have been able to fully insert a USB charging cable into my H990. It can only be partially inserted (i.e. will not click into place), and as a consequence it will not accept a fast charge. I don't see any debris in the USB socket, and have run a toothpick around the inside of the socket to try to clear out any blockages (although I can't see any). I've also tried different cables, and they all have the same problem. Can anyone suggest how I might resolve this?

I'm starting to have real problems with my USB plug. At first it would drop charger plugs when it was on the wall, so I put it upside down. But now I can't connect to the PC all the time either. I have to jiggle the plug a bit or even breathe down in it (the moist makes the connection better). Has anybody else had that problem and fixed it in any way? I suppose the plug is soldered on in such a way that it has to go to a workshop, right?
i strongly suggest you to send it for repair or resolder the base of the connection(this is user servicable provided you have some soldering skills) so it doesnt wiggle. i'd probly even suggest to hotglue the plug but before you do so make sure the plug is sitted properly and it does sync
the same thing happened to me and with a bit of jiggle the plug broke off and now its permenently damaged(ie it will never sync via USB again) so far with self repair i only manage to make it charge
i got no idea how to reattach a 10pin mini USB plug to my board and some of the copper tracks looks damaged which means if i send it to the shops, its a $500 repair and a board swap
I was always wondering how to speed up this unacceptably slow USB charging (If you are in a low signal area with bluetooth ON then the battery is drained far more quicker than the laptop can charge it ending up with a flat battery ). Finally I tested the output from the pins of the wall charger and my Laptop. Even when the laptop is powered off (no data exchange) the USB charging is very slow. The HD seems to send a ~1v pulse through D+ channel when to connect it to USB port (even when powered off the device seems to check if it is a USB data port), but with the charger it does not!, so we need to break this communication.
So I put a thin plastic film over the D+ and D- terminals of the USB cable and voila the device charges much faster..(slightly slower than wall charger - 25% slower, can be accounted for by the lower power output of the laptop USB port, the voltage of laptop usb port is 150-200 mV lower).
While I am typing this my HD has gained 9% charge with screen on!! . Natively it charged atmost 1% by this time with screen off.
Now I am looking for a permanent mod for my spare USB cable hacking off the data lines.
For those in a hurry with nothing but a HD with flat battery USB cable and a computer at hand, worthwhile using a thin paper over the inner two pins of the USB cable on PC side and plugging it in. (You do this at your own risk).
Hope it helps others too. Let me know your experiences.
With my Desktop USB port, charge rate is better than wall charger if you block the data pins. The port seems to be capable of 1.5 amp at 4.96 v
Also ensure that the USB cable snugly fits the mini USB port on HD.
Could this be also the problem why (my) Blackstone doesn't receive a TMC-signal with HyperGPS & iGO8 while charging in my car?
It's a genuine car charger from HTC, so I should say these pins are already "shut" from connection, or am I wrong?
I have a usb cable that is dedicatet for charging. It dosent have D+/- wires. With this cable on my laptop the charge time form about 20% is more than half of regular USD cable..
The cable was supplied with a car BT handsfree.
Regarding the TMC issue Im not shure, Try asking the guys that developed HyperGPS they might know, if not they might be able to fix if they arent aware of the issue
Interesting tip, thanks... I've lost my charger and have been finding it a pain to charge it using the USB port on my laptop.
I cut a small strip of paper from one end of a sticky note, and stuck the adhesive end to the outer flat surface of the USB plug to secure the strip in place. Seems to have done the trick, because the charging light is on and the PC hasn't detected the device. As for how long it takes to charge... will have to wait and see.
Also, I was wondering if there was any difference in charging speed (i.e. when charging via USB normally without using this trick) between activesync and file transfer mode?
I recently bought a custom 2 amp charger after the stock one died. Anyways, whenever I plug it in, I noticed that it would ask me whether I wanted to access the USB storage. Apps that need the SD card similarly, would terminate (ex: music).
Is there any way to solve this and to make the phone realize that this is a power outlet charger and not a USB charger? I think that the Epic drew about 650 milliamps or so charging and much smaller over PC (I think about 350 to 400 ish IIRC). It seems to currently only be charging at PC USB speeds as well and not the same rate as the stock charger.
Thanks in advance.
There's a way for the phone to tell if it's connected to a PC or AC adapter depending on a resistor shorting out two pins. Make sure you don't have anything other than the +5V and Ground connected.
I had the same thing happen with a car charger. Bridging / shorting the data pins causes the Epic to see the charger as a regular charger, and not usb for data or charging. This can also be done in the cable, itself, however, then you have the problem of having to cut part of your USB cable and re-tape or heat-shrink tube it.
There's a couple threads discussing similar problems/solutions:

Hi guys, I'm having problems charging my ms2.
seems that the connector has slowly deformed due to extensive use and it now does not hold the cable properly anymore.
Any suggestion how I can fix this without breaking the usb port? Maybe try another micro usb cable with better fit?
Hi,
I woke this morning to 19% charge after 6 hours.
When I try to charge it through the mains whilst turned off, it just vibrates every 2 seconds and shows a line across the screen as though something was going to show but stopped. Kind of thing you would see with a knackered screen.
Whilst I type this, I keep getting USB device not recognised as it connects and disconnects however the charge is still showing but doesnt seem to be putting anything into the phone.
The phone knows the charger is in, and shows but nothing is going in.Battery drain..
Charge only via Qi charger!!
PC also didnt see phone..
Try carefully cleaning the USB port with a needle or toothpick (under the USB pin as well!). Might be something metallic in there interfering with the connection.
I'm assuming other USB chargers and cables also do not work?

Try the cleaning, if that doesn't help try cleaning the contact points on the battery and its slot with a bit of denaturated alcohol and a cotton swap.(for sale in any drugstore).
If that doesn't help either, and you have one within reach, try another battery. And if that doesn't help, it's likely the motherboard.

Battery ok. With wireless Qi charger, everithing ok. Till 100% for 1.5-2 hours..
