Usbser.sys Windows 7 32 Bit

Hello, I want to communicate with the EFM32 MCU over a USB/CDC connection. As a basis for my source I used the usbdcdc example for the DK3750. Everything works fine, but installing the USB virtual COM port driver (EFM32-Cdc.inf) on Win7 is a mess. • Right mouse on the file and klicking Install results in an error. • If I use DeviceManager for installing the driver I get a big warning that the driver is not signed and shall not be installed. For me as developer no problem.

Belajar fingerstyle gitar.doc. Usbser.sys free download. Fix errors with missing sys files.

But not usable for end-users. Does anybody know how I create an end-user friendly installer for the driver?

Is it possible to sign the driver (.inf file)? Best regards, Wolfgang.

I too used the EFM32LG-DK3650 source, target is currently a STK3600 but will be my own hardware in about a weeks time when the PCBs come back from assembly. I can't install the USB virtual COM port CDC driver as it says it isn't compatible with Windows 7 64 bit! This IS a major problem for me as unlike Wolfgang I am not a Windows developer and have no idea as to what to do next. Moving to another computer is NOT an option as all the machines I have access to are running Windows 7 64 bit. I've also run into this problem. After adapting the USB virtual serial port code from the sample project an0042_efm32_usb_uart_bootloader, Windows 7 could not find a device driver. Then after the Windows alert vanished Windows completely ignores the USB serial port ( even after disconnecting/reconnecting).

After running a Ubuntu Linux VM in my Windows 7 machine the USB serial port communication works (with Linux, not Windows). Does Energy Micro provide a generic Windows 7 USB virtual serial port driver? I am also working on a CDC project and having a signed driver installer would make the end-user's life much easier. I have used the Si Labs CP21xx USB to UART bridge chips in the past with much success. They provide a signed Win7 driver installer that can be easily executed by the end user.

I want to use the USB functionality on the EM32 system to reduce component cost and increase flexibility. Energy Micro should be able to provide a similar solution for their USB enabled microcontrollers. In addition, SiLabs also provides the capability of letting customers use their VID for USB applications when the $2000 fee for a custom VID is not cost effective. They also sublease PIDs. Again, this capability should be available from Energy Micro.

Hi I am trying to install a gadget serial driver 2.4 on windows 7 and it comes as unknown device I always get this error 'the folder item you specified doesn't contain a compatable driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.'

I had checked the inf file and i am not sure how to get out of this issue. On windows XP it used to work. I am attaching.Inf file also txt format. I had gone through all the post and applied all suggestions but still stuck on same error. 'the folder item you specified doesn't contain a compatable driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.'

Interesting problem. I first thought you'd be between a rock and a hard place because as soon as you modify a driver's INF file, you break the driver's digital signature. So even if an INF hack got you past your problem, Win 7 wouldn't allow the driver install because it's no longer digitally signed! But did some more searching/reading and MAY have found what seems a solution: • Navigate to C: Windows System32 DriverStore FileRepository • Scroll down and look at all folder names that begin with mdmcpq.inf_amd64 • Open the one with most recent date (On my Win 7 x64 it's mdmcpq.inf_amd64_neutral_b53453733bd795bc) • Copy file usbser.sys to C: Windows System32 drivers Try installing again (using ALL the ORIGINAL driver files!).

You should be able to upload a zip file. No need to change the extension I'm confused by the file organization in your zip file. I want to see the your driver install files and how they're organized when do the install. Is there really a zip file included when you run the installation?

Across subfolders? > Just zip the top level folder(s) for me so i can see how they're organized when you attempt the reinstall Tell me the step-by-step of how you're attempting the installation > Do you plug in a physical USB device first?
