Zusammenfassung:	Methods and systems for synchronizing USB 2.0 isochronous IN and OUT transfer clocks over a non-USB network. One method for synchronizing isochronous IN transfer clocks includes: receiving, by a USB host adaptor (USBH), packets from a USB host; writing in each packet an indication of the time in which the packet was received by the USBH; sending the packets from the USBH to a USB device adaptor (USBD) over the network; and synchronizing the USBD clock to the USBH clock based on a property related to the received packets.
