It requires a license from Intel. A USB controller using UHCI does little in hardware and requires a software UHCI driver to do much of the work of managing the USB bus. [2] It only supports 32-bit memory addressing, [4] so it requires an IOMMU or a computationally expensive bounce buffer to work with a 64-bit operating system.

Consequently, support for this feature is absent from Windows Vista and later Windows releases. [64] [65] Microsoft rewrote their 1394 driver in Windows 7 [66] but networking support for FireWire is not present. Unibrain offers free FireWire networking drivers for Windows called ubCore, [67] which support Windows Vista and later versions.
Common device driver compatibility issues include: a 32-bit device driver is required for a 32-bit Windows operating system, and a 64-bit device driver is required for a 64-bit Windows operating system. 64-bit device drivers must be signed by Microsoft, because they run in kernel mode and have unrestricted access to the computer hardware. For ...
Standard USB hub ports can provide from the typical 500 mA/2.5 W of current, only 100 mA from non-hub ports. USB 3.0 and USB On-The-Go supply 1.8 A/9.0 W (for dedicated battery charging, 1.5 A/7.5 W full bandwidth or 900 mA/4.5 W high bandwidth), while FireWire can in theory supply up to 60 watts of power, although 10 to 20 watts is more typical.
A stack of external SCSI devices displaying various SCSI connectors. Parallel SCSI (SCSI Parallel Interface SPI) allows for attachment of up to 8 devices (8-bit Narrow SCSI) or 16 devices (16-bit Wide SCSI) to the SCSI bus. The SCSI Host controller takes up one slot on the SCSI bus, which limits the number of devices allowed on the bus to 7 or ...
DIMM modules connect to the computer via a 64-bit-wide interface. Some other computer architectures use different modules with a different bus width. In a single-channel configuration, only one module at a time can transfer information to the CPU.
A live USB is a portable USB-attached external data storage device containing a full operating system that can be booted from. The term is reminiscent of USB flash drives but may encompass an external hard disk drive or solid-state drive , though they may be referred to as "live HDD" and "live SSD" respectively.
