USB 2.0 7-Port Hub

Data Sheet Rev. 1.01

Figure 5 depicts an example that enable 5 downstream facing ports only, with port 3 and 2 as non-

removable device. As shown, the LED[4] is connected to the LED's, LED[2] left floating, and LED[3]

tied to ground, so that the FE2.1 would recognize that port 3 and 2 are non-removable devices. The

LED[6] is tied to ground and LED[7] left floating, thus the FE2.1 will report to system that only 5 ports

are available in this hub.

If the external EEPROM is not required, the TESTJ should be left floating. If the Hub Active Indicator

is not required, the LED and its serial resister should be removed together. If the port status LED's are

not required, LED[5:4, 1] could be all left floating with all their related Green/Amber LED's and

resisters removed.
