USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
For example, a USB 2 PCIe host controller card that presents 4 USB "Standard A" connectors typically presents one 4-port EHCI and two 2-port OHCI controllers to system software. When a high-speed USB device is attached to any of the 4 connectors, the device is managed through one of the 4 root hub ports of the EHCI controller.
The proprietary extension pack adds a USB 2.0 or USB 3.0 controller and, if VirtualBox acts as an RDP server, it can also use USB devices on the remote RDP client, as if they were connected to the host, although only if the client supports this VirtualBox-specific extension (Oracle provides clients for Solaris, Linux, and Sun Ray thin clients ...
Parallels Desktop for Mac is a hypervisor providing hardware virtualization for Mac computers. It is developed by Parallels, a subsidiary of Corel.. Parallels was initially developed for Macintosh systems with Intel processors, with version 16.5 introducing support for Macs with Apple silicon.

The absence of Ethernet may be mitigated by using a USB 2.0 to 10/100 fast Ethernet dongle based upon the Kawasaki LSI one-chip adapter (KL5KUSB102, for example), or a similar dongle based upon a Realtek chip; the Kawasaki Logic dongle requires a proprietary driver for macOS X, whereas the driver for the Realtek dongle is built into macOS X.
The virtual machine can interface with many types of physical host hardware, including the user's hard disks, CD-ROM drives, network cards, audio interfaces, and USB devices. USB devices can be emulated entirely, or the host's USB devices can be used, although this requires administrator privileges and does not work with some devices.
The boot code can also be loaded from CD/DVD, floppy disk (or floppy disk image) and USB storage, or it can replace existing PXE boot code on adapters that can be re-flashed. [7] The most popular free software to offer iSCSI boot support is iPXE. [8] Most Intel Ethernet controllers for servers support iSCSI boot. [9]
