Hi ALL; I sourced an USB ext, measures 4.5m. so with my USB mouse its about 6.5m.
Works fine but if I use the ext with my smartphone it doesn´t.
I know little about USB comm. but some say that the signals degrade over distance
which I can understand. Some say that it works with Ethernet cable, which I haven´t tried yet
Do You think it could be due to USB 5v supply?
Why would the phone need it, it has it´s battery?
If so, what do You think about the attatched circuit? It´s a youtube video, THANKs.
OH, please don’t suggest self powered USB hubs or other gadgets, it´s IMPOSSIBLE for me.
The following is a link to a video, do you thinkit works, helps? THANKs
