Symptoms

In Device Manager, navigate to “Universal Serial Bus controllers”, usually the last one, and then “Generic USB Hub” “Update Driver Software” or “Update driver”. Select the first option “Search automatically for updated driver software” in the next step to let Windows install the driver automatically. RMB bit and USB drives. Windows recognizes USB flash drives as removable devices due to the presence of a special descriptor bit RMB (removable media bit) on each of the devices. If the system determines that RMB=1 when polling the connected device using StorageDeviceProperty function, it concludes that this device is a removable drive. Other storage drives on PriceGrabber ranged from $15. One of the major improvements is the sleek construction of the device. The Lexar USB JumpDrive TouchGuard is a small, handy USB device made with fingerprint scanner to preserve owner's information secure. To be honest though, there is no more security that the JumpDrive Secure II. Removable storage includes USB drives, whereas USB connection (mobile only) excludes USB charging but includes other USB connections on mobile devices only.

Resolution

Drivers Lexar Media USB Devices

To resolve this issue, use one of the following methods, as appropriate for your situation:

Drivers Lexar Media USB Devices
  • Burn the installation DVD at a slower speed.

  • Use a better quality DVD to create the installation DVD.

  • Update the BIOS firmware for your DVD drive.

  • Use the Windows 7 USB/DVD Download tool to create a bootable USB flash drive, and then use the USB flash drive to install Windows.

More Information

This issue occurs for one of the following reasons:

  • The installation DVD is removed during the setup process.

  • A low-quality DVD was used to create the installation DVD.

  • The speed at which the installation DVD was burned was too fast.

  • The DVD drive cannot read the media.

  • The ISO file is corrupted.

Troubleshooting methods

Use one of the following methods to troubleshoot this issue, as appropriate for your situation:

  • Run the DVD on a different computer to determine whether the DVD works correctly.

  • Test your DVD drive by using an official Windows installation DVD.

  • Attach the ISO file to a virtual machine to check whether it is corrupted.

When you troubleshoot this issue, first check whether the ISO file is corrupted. Each ISO file that you download from the MSDN Subscriber Downloads website has a SHA1 value that you can compare with the SHA1 value on the MSDN Subscriber Downloads website. However, the Microsoft Volume Licensing Service Center (VLSC) site currently does not list checksums or SHA1 values.
To compare the SHA1 values for the ISO file that you downloaded, follow these steps:

  1. Install the Microsoft File Checksum Integrity Verifier tool. To download the tool, go to the following Microsoft Download Center website:

  2. At a command prompt, type the following command, and then press Enter:

    Fciv.exe <File name>.iso -sha1

  3. Verify that the SHA1 value matches the SHA1 value that is listed on the MSDN Subscriber Downloads website.
    For example, the following information is displayed for the ISO file for Windows 7 Enterprise with Service Pack 1 (x64) on the MSDN Subscriber Downloads website:
    File Name: en_windows_7_enterprise_with_sp1_x64_dvd_u_677651.iso
    Languages: English
    SHA1: A491F985DCCFB5863F31B728DDDBEDB2FF4DF8D1
    The following information is displayed when you run the command for the ISO file for Windows 7 with Service Pack 1 (x64):
    Command: fciv.exe en_windows_7_enterprise_with_sp1_x64_dvd_u_677651.iso -sha1
    Output:
    A491F985DCCFB5863F31B728DDDBEDB2FF4DF8D1
    en_windows_7_enterprise_with_sp1_x64_dvd_u_677651.iso

The ISO file is not corrupted if the SHA1 value on the MSDN Subscriber Downloads website matches the value that is generated when you run the command.

USB 3.0 Flash Drive Speed Tests - VID = 5dc (Lexar Media, Inc.), PID = b050

Welcome to Speed Tests Web site for USB 3.0 Flash Drives/Disks.
In this page, you can find the speed test results of USB 3.0 flash drives or disks, made by USBDeview utility.USBDeview make this test by writing a large file into the USB drive, and then reading back the same file to getting the read speed.The speed is calculated and displayed in Megabytes per second (MB/Sec). Be aware that all these tests are made by making asequential read and write operations of a single file. When you use multiple small files, you'll probably get much lower read/write performances.

If you want to test the read/write speed of your own USB drives and share the results with other people, you can follow the instructions in this page: Test and publish the speed of your USB flash drive.

There is also a summary page, which contains a summary of speed tests for USB drives that accumulated 5 speed tests or more.

Some Remarks

  • You can click the column headers of the speed tests table in order to sort by the desired field. For example, if you want to easily find out the drives with largest write speed, simply click the 'Write Speed' link in the column header.
  • The vendor name in the speed tests table is determined according to the VID (Vendor ID) of the USB device. The vendor names list was taken from the latest VID/PID list in http://www.linux-usb.org/usb.ids
  • The drive size displayed in the speed tests table is the real size of the flash drive, and it represents the largest file sizethat you can copy into this drive. Be aware that for most vendors, the actual size of files that you can store inside the drive is lessthan the offical drive size. For example, if you purchase a 4GB USB flash drive, the real drive size might be 3.7 GB.
  • If you can click the product name link, you'll get the list of all speed tests of products with the same PID and VID.
  • In order to keed this speed tests table reliable, I reserve the right to remove speed test entries that looks extremely unreliable.
  • Because the database is already quite large, the main page only lists the USB speed tests submitted in the last 60 days.
To more easily compare the speed of USB flash drives, you can filter the list according to drive size group:
1 GB or less2 GB Group4 GB Group8 GB Group
16 GB Group32 GB Group64 GB GroupLarger than 64 GB

Notice that the USB devices of last size group (above 64 GB) are not really flash drives. they are external hard disk drives plugged to USB. I originally created this Web site for flash drives, but because some people already submitted the speed test results of external USB disks, I added a group for them too.
