Coupling device and method for dynamically allocating usb endpoints of a usb interface, and exchange trading system terminal with coupling device

Abstract

The invention relates to a method and a coupling device (10) for dynamically allocating USB endpoints (31, 32, 33, 34) of a USB interface (30), which can be accessed using at least two applications, comprising: a USB interface (30) that has at least two ports (P0, P2, P4), each of which comprises at least one USB endpoint (31, 32, 33, 34); and a control device (20) for dynamically allocating the USB endpoints (31, 32, 33, 34). The control device is designed so as to preconfigure each USB endpoint (31, 32, 33, 34) which is required for the at least two applications by means of an initialization process, and thus the control device can switch the allocation of the endpoints according to the access using at least one of the applications without the USB endpoints (31, 32, 33, 34) affected by the switch having to be deactivated.
