Directly connected computer cameras from flooding, each can open, but if at the same time receive the hub can only open one, the hub is to start with the power of
I tried several computers, only one can open the two at the same time, the other can only open a computer, is the bandwidth? Drive? Power? Or what reason

CodePudding user response:

People don't have enough power

CodePudding user response:

Feel right upstairs, estimates that current is not enough, insufficient power supply

CodePudding user response:

The hub of independent power supply, power by rights should be guaranteed

CodePudding user response:

The building Lord, solved yet? I also encountered the same problem

CodePudding user response:

Have a can open at the same time two, is not the problem of the HUB, the reason is that PC,
Doubt is the problem that drive, even if the computer's operating system can be unified (after reinstalling), then see how the results,

CodePudding user response:

prawns with q with q

CodePudding user response:

With q, also encountered similar problems

CodePudding user response:

Try one plus the primary Hub,

For some enumeration information exactly the same equipment, some operating system driver cannot distinguish between them, then the application system may be its confusion, or as the same equipment,

You again a Hub, the path of the equipment information has changed, it is possible to identify,

CodePudding user response:

We solve the problem there are two major aspects:

COS, 1 the device enumeration return some unique information, for example, in the device descriptor support serial number string descriptor; When the host asked this string descriptors, the use of the serial number of the chip to generate this descriptor,

2 PC software increase equipment to identify additional information, such as path information (it contains the same port number) of the Hub, the handling system equipment change, detect the different equipment, new insert to open it, obtain the handle, and handle within software associated with the device path, so that when a device is offline right off the corresponding device handle,

Using one of the above measures can,

But the method 2 to HID device is not working, need to use more complex insertion order to identify, such as

For general users, the majority of cases into different Hub can bypass than bugs,

CodePudding user response:

Should be a driver problem, the computer default HUB is a driver, can't identify,

CodePudding user response:

I tried several computers can't, can only use a computer with usb interface, extend out can only use all the way, the other way to collect not to come out, also the resolution, appropriate is adjustable, or not, what is the solution? The camera complex network interface? It not only changed,,
