how many clients can I have without using a hub?

USB does not daisy chain, you need one output on a host or hub for each device you want to connect.> On Oct 18, 5:36 pm, Jack Klein <jackkl...@spamcop.net> wrote: > > On Thu, 18 Oct 2007 18:22:20 -0700, leel...@yahoo.com wrote in > > comp.arch.embedded: > > > > > I want to control a system including DSP+FPGA+FLASH+ADC+sensor by USB > > > port, program all chips by USB . what kind of bus shall i use? is > > > there any reference design projects online? > > > > > thanks! > > > > Haven't you already said you are going to use the Universal Serial > > Bus? > > > > Try to ask your question more clearly. > > > > -- > > Jack Klein > > Home:http://JK-Technology.Com > > FAQs for > > comp.lang.chttp://c-faq.com/ > > comp.lang.c++http://www.parashift.com/c++-faq-lite/ > > alt.comp.lang.learn.c-c++http://www.club.cc.cmu.edu/~ajo/docs/FAQ-acllc.html >

Try a USB host without a PC of the current version. Who do you think is talking about USB in 15 years ? Remember the 5.25 er floppies still to be seen in less recent scopes and such. The technology should be a bit more open than it is. Rene -- Ing.Buero R.Tschaggelar - http://www.ibrtses.com & commercial newsgroups - http://www.talkto.net
