Propojeji 2 PC pres USB kabel A-A???

[Src]

Cau vsichni,
nevite prosim nekdo jestli je to mozne (nekde jsem slysel ze JO, je to pry neco jako pres LPT1) a kdyz jo, tak jak to udelat Co k tomu je potreba a tak...
Diky

ja mam pocit (nezkousel jsem) ze ten kabel musi bejt prekrizenej .. .stejne jako na to lpt ... pak by moh stacit akorat Bahia USB Network driver

Je potreba USB bridge (relizovany napr. specialnim kabelem, nebo to muze byt implementovano primo v USB root hubu napr. na zakladnich deskach MSI se to jmenuje PC2PC).

Tady je oficialni vyjadreni z usb.org (aneb A-A je nejlepsi cesta jak si zkratovat napajeci zdroje v PC)...

Q5: How can I connect two PCs to each other with USB?
A5: You need a specialized USB peripheral known as a USB bridge (sometimes called a USB to USB adapter) to do this. Anchor Chips and e-Tek labs, among others, make USB bridges.

Q6: You mean I can't make a direct cable connection like a null modem?
A6: Correct. In fact, if you try this with an illegal A to A USB cable, you'll short the two PCs' power supplies together, possibly destroying one or both machines or causing a fire hazard. Even there were no danger to the machines from the problem with two power supplies, there still wouldn't be any way to get the two PCs talking to each other, since USB doesn't support that particular kind of communication. A reasonably priced solution to handle this need is the USB bridge.

Q7: So why do people make A to A cables, anyway? What kinds of cables do I need to connect USB devices together?
A7: A number of cable vendors seem to have reached the conclusion that USB is like a PC's serial port, only faster, so you need all sorts of special hardware to create the USB connection you need to make. This is completely incorrect. The only kind of cables you'll ever need to connect normal USB products are A to B cables, A to mini B cables or mini A to mini B cables of various lengths. Some special kinds of devices use nonstandard connectors and so come with their own special cable.

Q8: What if I want to network a whole bunch of PCs together with USB?
A8: If you need to connect just a few machines, USB bridges and a hub or two will work. USB was not designed to be a LAN, however, and there are certain safety hazards associated with trying to use USB with large numbers of PCs. There's also a large performance penalty compared to a real LAN. If you need a LAN, use a technology intended to be used as a LAN, such as Ethernet.

vida to jsem byl linej precist zas jsem o neco chytrejsi ))

no myslim ze se to menuje PCLINK)

[archaon]

Ano, opravdu to nejde. USB je navrzene na pripojeni periferii, je to stejny jako kdyby ste chteli spojit 2 pocitace pres disketovy mechaniky V tom krizenym kabelu je zvlastni radic, takze ty 2 pocitace vlastne nekomunikujou primo ale oba si jakoby pripojej ext. zarizeni, ktery je propoji.

jde to, ael jen u nejakyho starsiho MSI jeste to byla limited edition, kde byla fce PC2PC pres AA USB kabel....nekde na netu jsem videl nejak navod jak to zbastlit, ale byl tam zapotrebi najakej svab v prepoctu za 1k kc....sitovky jsou lepsi(rychlejsi, levnejsi...)

No vzdyt to uz je na zacatku tohoto threadu...USB bridge

[Bredator]

ku..rva to je tak kdyz nekdo neco necte a je linej...

spojit 2 pocitace pres disketovy mechaniky

Nad tym som uz rozmyslal - islo by to urobit, ale chcelo by to vyrobit vhodny hardware a software k nemu

[archaon]

A ze to neni spatnej napad? vzdycky sem chtel zaparit Quaka pres FDDcko mohli bysme rozjet vyrobu ve velkym a udelat dobrej byznys

[Fox!MURDER]

spis vymyslete jak to udelat pres SATA to by bylo celkem fajn

[Rainbow]

Cez obycajne IDE by to islo - chcelo by to nejaky procesor, nejaky pamatovy chip a nejake veci okolo. Procesor by zabezpecil emulaciu IDE zariadenia, do pamate by sa ukladali data. Pri zaplneni buffera by sa na druhej strane vygenerovalo IRQcko a driver by sa urobil tak, aby na to vedel reagovat (tzn. data odtial precitat). Mozte zacat s navrhom

[Bredator]

jeste by to chtelo opakovac(repeater)....to aby to bylo na vetsi vzdalenost...

btw...cez SATA by to bylo nejlepsi...(malo kabelu a velkej prenos)
