Question about Toshiba e800 Pocket PC

1 Answer

Can the e800 USB-host feed a 500mA Harddisk?

What I want to know is this: does the usb-host deliver enough power and is anybody able to actually work with a 1.8" or 2.5" usb harddisk without a separate batterypack or charger?

You may need to look up the hard drive on the manufacturers web site. They should list the spec's, including power requirements. In theory, sounds good though - anything to eliminate a power brick is good. Do you already have a hard drive you're thinking of using? If so, please post the drive model, manufacturer, etc - I can look it up at work in our files.

Belkin n600 db wiresless dualband usb adapter keeps shutting off


That's been a problem for years. Sleep mode turns off USB devices, and they seldom wake when the computer is activated again. To make sure this isn't the problem, you can
  • Go into Device Manager and under each USB Device, Power tab, disable "Let this device turn off to save power".
  • Edit Sleep Mode to not control USB devices.
  • Don't use Sleep Mode.
  • Unplug the adapter, wait a few seconds, plug in the adapter.
If none of these help, try a self-powered hub. The internal power supply lets you use about 500ma for each USB device, but some draw more current than that. The self-powered hub can deliver what's actually needed for the devices.

What local store can I buy a dual power USB cable for my WD Passport?


It depends if the usb port on your system can deliver a full 500ma current or if it is just 100ma. About "local store" - it is hard to tell without knowing what continent are you from.

Usb over current error 701


The USB port can only deliver aprox. 500mA. If your USB device such as a scanner etc. draws more current from the USB port then you will get this error message.
The solution is you use a powered USB device OR use a powered USB hub and connect this to the computer/laptop's USB port and then plug the USB device into the powered USB hub.

What is a portable USB (2.0) hard drive ??? Is it just a big USB ? Please tell me everything about USB (2.0) hard drive.


First of all, USB is an interface, that can be used for various computer peripherals, like a mouse, keyboard, printer, storage devices etc. Additionally, the USB interface is able to deliver some power (5V 500mA), which is quite enough for many devices. USB 2.0 is the newer, faster version of the original USB 1.1 specification.
Now for USB storage. Basically there are two types on the market. First are Flash (solid-state devices), usually in form of a "dongle" (called pendrive, stick). They store information in semiconductor memory. Second are hard disks, just like the ones installed in desktop and laptop computers - they store information on magnetic media.
Hard disks in a small enclosure, equipped with special interface, that enables them to be connected via the USB interface, are "portable USB hard drives". Many of them can be powered from the USB socket alone, some need an additional power supply.
With today's technology, hard disks can have 10-20 times larger capacity than flash devices, so they are still indispensable when you want to store a lot of big files (like pictures, movies etc), or back up the contents of your computer's hard drive as a safety copy.

I have a WD 1600U EXT USB DRIVE. IT WORKS GREAT ON MY DESKTOP; HOWEVER WHEN I PLUG INTO MY LAPTOP, THE BLUE BLICKS, MY LAPS ACKNOWLEDGES USB CONNECTION, BUT IT JUST LOADS, STOP, RELOAD UNTIL I UNPLUG IT


I have had the same problem with laptops and USB drives. The external drive simply is not getting enough power.

The two solutions that seem to work are:

1) External power adapter for the USB Drive. Many external USB drives have a micro power plug next to or near the USB plug. A 5 Volt adapter (which plugs into the wall OR one that plugs into your cigarette lighter plug in a car) will cure this problem.

2) Some external USB drives come with a plug which has (2) USB plugs which plug into your laptop (laptops typically limit the power for each USB port) and one plug on the other end for your USB drive.

I have two Gigaware IDE enclosures with USB


My guess is not enough power is available to run both devices at once.
Do your hubs have a external power supply?
Do the IDE Enclosures have a port for their own connection to a power supply?

The available power on a the pc's usb port is about 500ma (from memory)

Have a look at how much power your IDE disks actually need. It should be written on the label.
If the total is more than 500 ma then you will need to provide more power either via your usb hub or to the enclosure directly.

Hope this helps.

Targus Travel USB 2.0 4-port Hub


sometimes usb hard drives will not work through a usb hub.
if the drive works connected to the laptop but not the hub then that's how you'll have to use it.
it's also possible the laptop cannot power both the hub AND the drive, in whaich case you'll need a powered hub (one you plug in to the mains).

Connection to PC no longer working


Sorry for the delay. The hotel wireless connection took a dive. If the camera works OK and it is just a message then go to Control Panel>Device Manager>Universal Serial Bus Controllers>USB Enhanced Host Controller>right click to select properties>Advanced and then check the box that says "Do not tell me about usb errors". That will stop the error messages which only mean that the camera is drawing slightly more than 500mA which is a USB 2.0 feature that you can disable to revert to USB 1.1 but not necessary if the camera works. Each of the Host Controllers has a check box like that. The USB Root Hubs below that have similar checkboxes to Reset if you ever get a message that the Root Hub needs to be reset just for your own info. This is a common annoyance and is probably more due to the USB cable quality than the camera actually drawing more power. Feel free to repost if you have any other concerns. Steve Medley

Usb port on Acer aspire 5050


Be safe rather than sorry, get yourself a Powered USB Hub.

One of the problems with USB is that a device is only allowed to draw up to 500mA of power (100mA on first connection). So, if you buy a non-powered hub, it will only support one high-power (500mA) peripheral, and the other ports on that hub may be useless. Plug a mixture of devices into a non-powered hub and some might work while others might not. Since people expect to be able to plug any USB device into any USB port, I think this is really bad. Using a powered USB hub generally eliminates the problem.
