When I connect B, Device Mgr shows it as USB Serial Device (COM4) (device A). I can't update the driver for either because Windows doesn't see the correct driver ie. If I go to the Arduino driver folder to load the proper driver, Windows will not load as it's looking for UART drivers. It's as if the 2 devices have switched identities. System must have pci simple communications controller driver installed correctly. It displayed in Device Manager list with Yellow Mark in case driver not install. To find it you need to go Device Manager Other devices pci simple communications controller. When you install the driver then you don’t see yellow mark again. The PCI Simple Communications Controller is a generic label given by Windows to PCI boards installed in a PC when the drivers for the device are not installed. Let’s try the following methods and check if it helps.

Windows device driver information for Symbol USB COM Port Emulation

• How do i install the latest driver for PCI Simple Communications Controller and how do I solve problems with PnP devices as I need this to install my printer? Ihave just updated from windows 7 to windows 8. Ps, not a techy so I need things explained in simple terms.
• Finding the serial port (which constantly changes, every time you plug a device in), is just matter of checking device manager (see above). Mass Storage It should be a simple matter of opening the drive, in this case, double click on “D”, to get at the info.html page.

The Symbol USB COM Port Emulation is one of the Universal Serial Bus interface modes that is backed up by Symbol scanner equipments. In this mode, a Symbol scanner device attached to a personal computer through a USB cable functions as if the equipment is connected through a computer port. This driver makes a virtual computer port in the personal computer matching the equipment that is connected through USB. It is highly suggested that there should be a minimum of 5 MB of hard drive space on the system to be able to set up the program. The software added in the distribution package is structured to work with Symbol Synapse scanners. The virtual computer port device will be read-only. The serial baud levels, RS232 handshake lines, modem status and control register configurations are not supported. The inter-character delay and FIFO controls as in UART are not supported.

Outdated Drivers?

Unless you update your drivers regularly you may face hardware performance issues.

To check your drivers you should manually verify every device on your system for driver updates

The Symbol USB COM Port Emulation is a standard cable connection interface on personal computers and other peripherals. The USB ports permit independent electronic devices to be linked though cables to a computer. USB or Universal Serial Bus is an industry standard for short-distance digital interactions. USB allows files to be transported between devices. It can also supply electric power across the cable to equipment without their power source. There are two versions of the USB standard, the corded and the cordless version. The corded version involves cables and USB ports. There are a lot of consumer electronics backing up the USB interfaces. There kinds of devices are most normally utilized for computer networking like USB network adapters, USB broadband and cellular modems for Internet access and USB printers to be shared on a home network. For computer to computer data transfer without a network, USB keys are utilized to duplicate the data between equipments. It is highly recommended you run a free registry scan for Windows and Symbol USB COM Port Emulation errors before installing any driver updates.

Microsoft provides a SCSI Port driver as a standard feature of the Microsoft Windows storage architecture. The SCSI Port driver streamlines the Windows storage subsystem by emulating a simplified SCSI adapter. Storage class drivers load on top of the port driver. This means that you can write storage class drivers for Windows with minimal concern for the unique hardware features of each SCSI adapter.

The emulation capabilities of the SCSI Port driver also allow you to develop minidrivers that are much simpler to design and code than a monolithic port driver. In other words, using the SCSI Port driver allows you to focus on developing a miniport driver that handles the particular features of your adapter.

To use the SCSI Port support routines, link to one of the SCSI Port support libraries, scsiport.lib or scsiwmi.lib. These SCSI Port libraries handle all interaction between the miniport driver and the hardware abstraction layers (HAL) of the operating system. Miniport drivers must not link directly to the HAL support library, hal.lib, nor should they link directly to the ntoskrnl.lib or libcntpr.lib support libraries. SCSI miniport drivers that do so are not eligible for a Windows logo.

The following sections examine the key features of the SCSI Port driver.

The Windows storage architecture also provides the Storport Driver, the recommended alternative to SCSI Port for high-performance devices.
