A dynamic power management system for USB hub and method thereof are described. The dynamic power management system includes a host device, a power unit and a hub device. A power management module disposed in the hub device dynamically adjusts the power-supplying statuses of ports in the hub device and further reduces the cost of power transformer externally connected to the hub device.

Power management system for dynamically downgrading or upgrading the speed of individual USB ports on a USB hub based on available and requested power

A storage device for refreshing pages of a flash memory comprises a flash memory, an ECC detector and a controller. The flash memory has a plurality of pages, and each page comprises a data area for storing data and a spare area for storing error correction code (ECC) corresponding to the data. The ECC detector is used to get the number of error bits of each page. The controller coupled to the ECC detector is used for storing data and ECC in a first page to a second page when a number of used bytes of the ECC stored in a spare area of the first page exceeds a first predetermined value. A number of used bytes of the ECC stored in a spare area of the second page is less than the first predetermined value. The second page is a blank page.

Storage device for refreshing data pages of flash memory based on error correction code and method for the same

An electronic apparatus having switching unit is described. The electronic apparatus includes a first peripheral device, a second peripheral device and a switching unit. The first peripheral device communicates with the host unit. The second peripheral device communicates with the host unit and the first peripheral device, respectively. The switching unit switches to the host unit and the first peripheral device for allowing the host unit to access the first peripheral device via a first path. The switching unit switches to the host unit and the second peripheral device for allowing the host unit to access the second peripheral device via a second path. The switching unit switches to the first peripheral device and the second peripheral device for allowing the first peripheral device to access the second peripheral device via a third path.

A method for adjusting the PCI Express lane ordering is disclosed, comprising the following steps. The first packet associated with a first PCI Express lane ordering is sent to the peripheral device. The peripheral device replies the second packet associated with the second PCI Express lane ordering. Whether the PCI Express lane ordering is correct is determined in response to said second packet. The first PCI Express lane ordering is adjusted while the first PCI Express lane ordering does not match the second PCI Express lane ordering. Preferably, the adjusted PCI Express lane order matches the normal order or the reverse order. Then, reset and reinitialize the peripheral device. The resetting step can be accomplished by sending reset packets, or changing the common mode voltage level in order to reset the bridge chipset of the PC.
