A4: If X is less than 25m or so (see previous question), buy a bunch of hubs and connect them serially with 5m cables. If you need to go farther than that, put another PC, or maybe a laptop, out where you need the device to be and network it with the first PC using something that's intended to be a long-range connection, such as Ethernet or RS-485. If you need to use nothing but USB, consider using USB based Ethernet adapters to hook the PCs together.

You can go 5 meters or around 16 feet from a computers USB port or from a powered USB hub to a USB device. Back To Questions

Build a USB bridge that acts as a USB device on one side and has a USB host controller at the other end. Use a long-haul signaling protocol like Ethernet or RS-485 in the middle. Using cables or short-haul fiber, you can get ranges upwards of a kilometer, though there's no reason why the long-haul link in the middle of the bridge couldn't be a pair of radio transceivers or satellite modems. Embedded host solutions capable of doing this already exist.

No, but this is being worked on. If you would like to help, please first read the libnetmd archive and if you still feel you can help or you have discovered something new, subscribe to the list and post your information. It will be appreciated.

The exact error message looks like Could not find USB device (vendor 0x0000, product 0x0000). Make sure this device is connected to the computer You have to set up the permissions on your USB device correctly. See Section 4.3, "Setting up permissions for USB ports".

The requirement is similar to that of USB 1.1, but all components will have to be USB 2.0 compliant. A successful USB...

If you have purchased a seat license of a ProjectMatrix product with a USB security key you will still need to register the software.

A3: With the maximum of 5 hubs connected with 5m cables and a 5m cable going to your full speed device, this will give you 30m of cable (see section 7.1.19 for details). With a low speed device, you will be able to get a range up to 27m, depending on how long the device's cable is. With a straightforward cable route, you will probably be able to reach out 25m or so from the PC.

The exact message looks like *** Error ('Could not claim the USB device') *** Could not claim interface 0 (Operation not permitted). Make sure no other program or kernel module (e.g. dc2xx or stv680) is using the device and you have read/write access to the device. You have to make sure that no such kernel module is loaded and that you have set up the permissions on your USB device correctly, such that you have (non-root) write access to the camera device.

Before inserting your USB memory stick, please log in to the machine directly (not via SSH from another system). Logging in at the console will ensure that the USB memory device is mounted with you as the owner. It is safest to insert the device into one of the USB ports on the front of the computer (rather than those on the back or on the keyboard).

It might seem that the USB device is fairly slow, especially when writing to the device. This is for two reasons: Firstly, USB devices are substantially slower than hard drives or other high-speed media; furthermore, larger-capacity flash memory devices are often slower for write access than low-capacity devices. Secondly, we mount the device in "synchronous" mode, which makes writes seem slower than the more common "asynchronous" mode.

Version 5.9 of the Pocket PC application requires Pocket PC 2003 Second Edition. Most manufacturers will have updaters available for their handhelds. Unfortunately, HP is not planning to do this for iPaqs. If you are unable to update your Pocket PC, you may use this installer. You will see a warning that the application may not work with this version of Windows. You may ignore this warning.

Close all the files accessed from the USB Device. Click the green icon on the system tray. Click on "Stop USB Mass Storage Device" A window would appear "The USB Mass Storage Device device can now be safely removed from the system." Click "OK" and then unplug the USB Device. Note: The green icon do not appear on Windows 98SE Operating System. Just make sure no files are open and then remove the USB Device.

Under certain circumstances the T8 will fail to recongize a USB device which is attached to the T8 before turning ON the T8. As a workaround, try turning ON the T8 first, then attaching the problematic USB device. This may allow the T8 to recognize the device properly.

The answer is no, your AC/USB Boostaroo isn't defective. What you are hearing is the transient noise that your PC produces naturally through oscillation of your power supply and the hard drive whine caused by its mechanical spin. These noises are much more common in older PC's, but a lot of newer PC's have noise filters built into the PC's USB ports, which eliminates these noises. If this problem is occurring, we recommend using the AC power supply for your Boostaroo instead of the USB cable.

You can identify whether your PC has Hi-Speed or not relatively easy. Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present. Windows 98 systems may use a different name, because Hi-Speed USB drivers in these operating systems are not provided directly from Microsoft (Windows ME, 2000 and XP get their drivers through Windows Update). These drivers are provided by the manufacturer, and may carry the maker's name (i.e.

Waterpicks are frequently recommended by dentists for persons with gum disease; solutions containing antibacterial agents like chlorhexidine or tetracycline, available through a dentist's prescription, can be added to the reservoir in these cases.

There are many different symptoms when your computer is infected with a virus, but common ones include: The only way to be certain whether there is a virus on your machine is to scan it with an up-to-date anti-virus program. If your PC is infected with a virus, you may not be able to access any anti-virus website or you cannot update the latest virus definitions file effectively. You must download the standalone intelligent updater with the latest virus definitions and scan your PC with it.
