QUESTION: Dear Prof Cleggsan


Can there be advantages in manufacturing Ethernet based USB Switches and Hubs similar to Ethernet 10/100 MBPS, Gigabit Ethernet switches for sharing computers and peripherals ?.

For example :

24 port Ethernet Switch / Hub having USB Ports on the Device, the Data transfer will be through USB Cables connected from USB Ports
to computers (servers,laptops,workstations,peripherals etc) having USB LAN controllers.

i.e. Comparing data transfer speeds offered by 10/100 MBPS Ethernet, Gigabit Ethernet v/s USB technology.

Awaiting your reply,

Thanks & Regards,

ANSWER: I am not sure of the need for such an application/solution and if it has merit.

Further, there may be compatibility issues or manufacturing restrictions from the licensees.

But, I am not an expert in this area and I refer you to other experts for realistic opinions about your proposal.

QUESTION: Dear Prof Cleggsan

Thank you.


Do you feel USB 3.0 technology can overcome this limitations in terms of data transfer speed and distance over Ethernet ?.

i.e. USB 3.0 LAN/MAN/WAN Networks over Ethernet 10/100 MBPS, Gigabit Ethernet Networks.

i.e. USB Cards, USB adapters, USB Cables, USB Hubs, USB Switches, USB Devices etc.

Awaiting your reply,

Thanks & Regards,

Sorry, I am not an expert in this question and I think it requires much investigation to learn the potential application to systems.  But, USB 3.0 is an improvement over older versions for sure.  Comcast cable company in the USA is now using a proprietary cable service for Internet delivery which will support 100 MBPS downloading service to USA homes and business. So, the world is always looking for more speed and data rates.  

Have a happy day.
