My SPV m1000 stops charging when PC is turned off

After using the XDA 1 since its release, I managed to get a SPV M1000. many advantages however Video and Camera are not very good !
Problem:
I charge from my sync when my desktop PC is on however as soon as I swich my desktop PC off the USB loses power ? and stops the charging. Is there a setting for this ? or is this normal ? my XDA 1 does charge from the USB when the desktop PC is off !
any ideas please

however Video and Camera are not very good !

no phone or webcams (cmos chip video )that i've seen is very good quality, suppose thats the price one pay for lower power comsuming and cheap production cost and smaller size
about the xda2 then at least my cradle have a connector where i can plug in the charger adaptor if i want to charge without having my computer on
unless orange use a different cradle which i doubt then you too can plug in that charger if it dident come with the device you can prob buy it or use any charger with the same connctor and power voltage

Im sorted !
Stupid me !
after using the XDA 1 sync for so long, I forgot about the adapter being pugged in to the sync. However the handbook that came with it does not advise on charging so not entirely my stupidity.
thanks anyway

I think it depends on your PC's motherboard too. I have USB power to the cradle all the time, even when the PC is shut down. I don't use the power charger with the cradle ever - it's only for emergencies.

I agree. I have an abit Nf7-s motherboard and the usb port still delivers power when my computer is down

not if you pull the plug it dont
it all comes down to if the vsb 5volts standby
is connected to the usb
when there is an option in the bios to let keyboards turn on ones computer then it should work
if the usb is on a pci card like some of my usb2 cards is then it's up to the card
pretty sure mine dont

Fast USB Charging on O2 XDA Mini

HI Friends
Do you hv any software to carry out fast USB Charging option, to charge my XDA with same speed as done by AC Adapter...
I have seen that other WM2003 models has this option.... like in HP 6515..
Thanks
Manmohan

Interesting... I've got a desktop holder which has to modes: charge-only and normal sync/charge mode. I wonder wether charge-only mode "enables" fast charging or wether the AC adapter does something special...

If i'm not mistaken, the typical USB port outputs 5V of power at 500mAh (milliamp-hours). And in my case, my shipped charger outputs 5V at 1000mAh . using the supplied charger would charge my Magician twice as fast compared to the USB (explanation below). I think even USB2.0 ports still give out power at 500mAh.
The Magician's battery is rated at 1200mAh. Charging through the PC's USB port would take roughly 2.4 hours. Using the supplied charger, it would take 1.2 hours. Simple equation for charging is, battery rating (mAh) divided by charger rating [so that's 1200mAh/500mAh for USB]. Disregard the voltage for now unless you plan to make your own standard/portable charger. Rule of thumb, refrain charging the battery with a higher mAh rated charger.. It will damage the battery in the long run.
Hope this helps. Cheers!
Although if you could somehow control charging via software that'd be a nifty tool...

i doubt it since max current USB can provide is 500mah as any more would damage the port and probably the board.

Hello
Yup, jedhonx your right! Its the amount of power supplied! There is no way that you could use a software to charge the device in USB at faster rates.
The only way it could be thought of is like, if your device processor is running at certain spped, it consumes some power. When it runs at lower speed, it consumes lesser power and so if the software could make your processor run low or to shut down other programs maybe would show you an incresed speed of charging!

what about taking two usb ports with such a hard disk cable?

One of the following three thing WILL happen if ALL of them...
1-Fried Motherboard
2-Fried Battery
3-Fried Device
The first can happen because the USB ports will send energy to each other, the other two because voltage WILL duplicate... Think like this, when you have a device that uses "normal" batteries like a remote or a portable cd-player that uses two or more 1.5V batteries they use it because the device works with 3V (2*1.5V batteries)... Hope I made myself clear, because my english is quite rusty...

Well if you link USB ports to increase voltage it's true that it'll probably kill the mb. But linking 2 UBS connectors to increase amps is no problem and often done. You end up getting 5V 1A output. You could even link more ports to further increase the maximum supplied amps, alltough I never tested more than 3.
Linking 2 ports in a way that increases amps will NOT fry the mb, will NOT fry the battery and will NOT fry the device.
I'd say give it a try and see if it charges quicker.

Actually I think it depends on how many separate USB chips are connected to the USB ports. On one chip (or better say channel) can be more than one port be connected on the computer (like with a passive hub). In that case, connecting two USB cables in parallel doesn't change anything. Otherwise you could connect the cables in parallel and simply get more current at the same voltage (not to mix up with setting batteries in serial).
There are USB chips on the market that supply more than the specified 500mAh, but I suppose the Magician itself detects a USB connection to the computer. I remember that the first ROMs could only be loaded by USB chargers when Pin5 was connected to Ground, which was never necessary when a real USB connection was established to the computer. USB connections to the computer only use 4 Pins. This tells me that the Magician distinguishes between a connection to the charger and a connection via PC USB and limits the power drain correspondingly. If that is the case, connecting a cable with two USB ports doesn't help, it's still recognized as PC USB connection by the Magician.

it maybe OOT, but still relates. my magician can only be charged by usb cables. wont work on ac adapter. it has been going for few months and it really bugging me since it takes 4 hours to charge through usb cables.
i did try hard reset and no change .

HI Friends
I appreciate that you are trying all your mind to find the solution..
I believe that O2 provied AC Adapter wont pass additional current to screw up the battery life as it is provided by O2 Manufacturer itself. If Adapter takes 2 Hrs to completely charge the O2 Mini, then this can be done by USB cable also.
Also if you see in any other PDA running windows mobile 5 you will see an option of "fast USB Charging"..
It means that it can be done, but we need to find out how it can be done.
Thanks

[Q] Charging TAB from a PC USB or USB Hub

I setup a self-powered USB2.0 hub which has a 2.5AMP power adapter. I used a dual male (split) to single female USB cable and plugged the TAB USB cable into that.
This same dual cable & hub works fine to power an external USB hard-drive which won't work with just a single cable for power. I would think with 2+ AMPS it should charge the TAB "normally" (with no "x" on the battery indicator) but it does not, the "x" remains. All other devices have been removed from the hub.
Anyone else been able to get a normal charge off a PC or USB hub with a split cable? It's such a pain to have to put the TAB on the wall charger then switch it back to the PC.

when the screen is off the device charges, despite what the battery display says.

Correction, it trickle charges. Very slowly.

I understand that but I was under the obviously incorrect impression that if you used a double male USB to single female USB cable you would get a normal charge since there is more power available. Is the charge rate dependent on the TAB seeing power on a specific pin of the cable telling it that a charger is connected and not a cable to the PC? I'm connected to a self-powered hub with a big 2.5amp power supply and nothing else connected to it.

OTG and charging at the same time?

Is it possible to attach external devices to the Fire HD 10 via OTG and charge the Fire HD 10 at the same time using those special OTG+charging adapters?

Yes you can. It's also helpful if you want to use a wireless usb controller since it needs the power boost. Here's what I use: https://www.ebay.com/itm/Left-Angle...361414?hash=item48830dbec6:g:rQsAAOSwMmBV5RRC

My pleasure! I have a bluetooth keyboard case. I mostly use it for flash drives and it charges while in use. I also have those devices plugged into my firesticks at all times so I can transfer video files easier and never had a problem

Thanks for the confirmation. I had been using this cable (https://www.amazon.com/Tendak-Micro...07828&sr=1-2-spons&keywords=otg+y+cable&psc=1) for my Nexus 7 I had installed in my dash, and for some reason it just doesn't work with my HD 8. Even with the USB DAC not connected, the cable registers power, charges for about 30 seconds, then says it's not connected to power anymore. don't have this issue with the Nexus, or with any of my other power cables, but that's the only OTG angle cable I have.
I'll try the one you use, but I'll have to use a Micro USB angled extension to make it fit in the dash. Unless someone else knows of an OTG y cable with an angled plug that actually works for the HD 8?
Update: I've bought two additional otg cables from Amazon, and one will work for the usb device, but doesn't charge the tablet, the other charges the tablet, but won't work for the usb device. After testing both of these several times, they both started to have the same behavior as my other one, it shows charging for a few seconds, then stops, but continues to power the usb device. If I connect a normal power cable it will stay in "fully charged" mode forever and Automate reports power is connected. I'm starting to get really frustrated. I'm pretty sure it is actually charging, because when I left it connected like that for an hour, it never moved from 85%, but then as soon as I plugged in a normal charging cable it started "charging" at about 6% per minute, and said 100% within 3 minutes. Not even a QC 3.0 can do that. I'm so confused.

SM-T510 Tab A 2019 10.1 Otg with charge and data?

Hello guys,
Does anyone knows if there is a otg cable/hub that can power the tablet and be able to use data like usb connected at the same time?
Thanks

The 2019 tablet does not need this, since the port is USB type C albeit USB 2.0; I have connected mine to a hub and have pass-through charging and data. OTG is not really a thing any more since USB type C came about.

Can you share the type of hub you have been used?
Is the charging speed fine?

Kingston Nucleum. This tablet is in my car and the hub receives power from a 12-14v converter providing USB C PD and USB 3.0 fast charge. Ultimately, the hub defaults charging voltage to that of the lowest device connected. In my case a Sandisk SSD and a Meizu HiFi DAC Pro. This generally means that charging is slow, however it depends on your configuration. I'd say that the charging speed is fine, however it only charges when the car is running or in accessory mode and the tablet is always on in that state. As such the excess power it uses to charge whilst running is only a little more than it uses. It might charge faster if I power the hub from the USB C PD port, however I don't know if this is just pure amps or whether it negotiates higher charging voltages. I don't know if the Nucleum hub allows negotiation of higher charging voltages.

Nice, i'm using for the same purpose.
In my dash car
I'm also using MacroDroid for automation.
My issue right now is how should i leave the tablet when i turn ignition off.
I Think i will just shut it down, but i don't like to wait 30 seconds to but again when i turn it on.
What do you do in your case?

I'll have to check out MacroDroid. I'm currently set up with AutoMate, however there's a few annoyances which I think need ironing out. Vanilla Android Auto might not be the most exciting, but it's certainly the most friendly for driving safety.
I leave my tablet as-is. AutoMate automatically wakes the tablet into car mode on USB power and goes to sleep when it loses that. My car (Chrysler 300C) has accessory power for 30s (I think I can increase this in the EVIC) after the ignition is turned off which keeps the charger energised, and by extension the tablet. I'm not too bothered about having to boot up the tablet if it does discharge its battery to shutdown. I think it's maybe a week or so for it to do that, likely less when the tablet ages. As long as it charges and runs on the supply happily I think we're good. In that instance, I might have to see whether an auxiliary power bank would be a workable option. Not at this stage though. Bear in mind that most modern car head units still take about the same amount of time to boot as an Android tablet anyway.
I'm having minor USB issues myself, however this is down to the cable I need not being available. A lot of USB C "charging" cables are only pinned for power and not data. This might be part of any USB C issues you might be having. I myself need a USB C male with a tight 90° or 180° turn, out to a USB C female for the hub's pigtail. I might have to make the choice to fabricobble myself a USB cable just for this purpose....
This is a photo of the install, prior to me wrapping it in 3M brushed black steel vinyl.

I'm updating all of my comments in various threads on this. My setup with the Kingston Nucleum hubis having minor issues. The tablet still needs to be powered up before I turn on the car or at least supply power to the hub. It seems that if this is done the other way around, that is, to power on the car accessories (and hence the hub) then it seems to end up staying as the "device in charge" of the USB network. The tablet charges (slowly) but doesn't mount the USB SSD drive or the USB DAC. If the tablet is powering the hub (in charge, so to speak) then applying power to the hub via the car accessory supply has it working as expected. This does mean that the tablet ends up with a power drain when the car/USB power supply is powered down which isn't ideal. I've gotten into the habit of turning the tablet off when I park for long periods of time, however I need to boot it up to "take charge" of the USB hub network before I can start the car. It's a bit of a bummer.
I'm unsure whether this is a tablet hardware/software issue, the hub or whatever. Going into Android settings and trying to alter the default USB behaviour returns the message that it "cannot switch roles" or something along those lines. I'm beginning to think that this might be the USB hub refusing to switch/relinquish power supply roles once it has external power and hence not allowing the tablet to mount drives or see connected USB devices. It's weird behaviour, because you'd imagine that if the hub were connected to a laptop this would be a common action.

If it helps, I've read that OTG function is not included by Samsung for their device's USB ports. I've been trying to connect some together to perform file transfers with no success. However, I have been able to transfer and charge simultaneously between my SM-T510 tablet and PCs with the USB configuration set to file transfer.
