светодиоды немного ярковаты и на мой взгляд — попса 90-х
USB2 did indeed introduce Transaction Translators for attaching FullSpeed and LowSpeed devices to a HighSpeed hub. However not only did the USB3 spec fail to follow this precedent, but it requires that USB3 hubs use the old USB2 protocol over the two original signal wires of it's uplink for all downstream HS/FS/LS devices. All USB3 cables must carry both the old HS/FS/LS signal wires and the four new SS conductors. USB3 hubs are effectively two separate hubs for two separate buses. They may not actually be two separate chips, but since they're separate logic blocks, they may as well have been.superuser.com/a/624312/28381
XHCI root hubs do not have this constraint: they may provide a full USB2 HS channel's worth of bandwidth to each port.
[...]
At this point, implementing a USB2 controller driver on top of an XHCI stack would be non-trivial; maybe that's why we haven't seen one.
Hi, Dear Mikhail,
ORICO really appreciated your work and support for ORICO product.
Thanks for your good suggestion for ORICO A3H7, 7 port USB3.0 HUB, LED design and USB chager design. I will discuss it with ORICO concerning guys together. We will introduce your suggestion into ORICO new products and OEM service for customers in future.
Thanks again. :-)
Однако, практически у всех продающихся хабов — повторяются одни и те же недостатки (на мой взгляд):Имхо, у многих, очень многих хабов с внешним питанием самая серьёзная болезнь — постоянно выдают 5в в комп (диод[шотки] не распаян или вообще не предусмотрен), иногда с печальными последствиями. На части хабов что видел и конденсаторы не распаяны.

Какой мощности у него блок питания?
