USB hubs that are transparent proxies Transparent proxies take the USB 2.0 input and present it as USB 2.0 to the MacBook Pro . The Mac or Catalina then will do something wrong and the USB 2.0 devices will freeze \/ become unresponsive at some point (minutes or hours after being attached).<\/p>\n Terminating proxies take the USB 2.0 input, terminate it, and present it as a fresh input that is USB 3.0 to the MacBook Pro . Everything is good in this scenario.<\/p><\/blockquote>\n \u4eca\u5f8cApple\u306e\u306a\u3093\u3089\u304b\u306e\u5bfe\u51e6\u304c\u6c42\u3081\u3089\u308c\u308b\u3053\u3068\u306b\u306a\u308a\u305d\u3046\u3067\u3059\u3002<\/p>\n","protected":false},"excerpt":{"rendered":" 2020\u5e74\u30e2\u30c7\u30eb\u306eMacBook Air\/MacBook Pro\u30e6\u30fc\u30b6\u30fc\u306e\u4e00\u90e8\u304c\u3001\u30a2\u30c0\u30d7\u30bf\u3084\u30cf\u30d6\u7d4c\u7531\u3067\u63a5\u7d9a\u3057\u305fUSB 2.0\u30a2\u30af\u30bb\u30b5\u30ea\u304c\u4f7f\u7528\u3067\u304d\u306a\u304f\u306a\u308b\u3068\u3044\u3046\u4e0d\u5177\u5408\u3092\u5831\u544a\u3057\u3066\u3044\u308b\u4e8b\u304c\u308f\u304b\u308a\u307e\u3057\u305f(MacRumors)\u3002 […]<\/p>\n","protected":false},"author":2,"featured_media":80059,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"swell_btn_cv_data":"","footnotes":""},"categories":[4],"tags":[325,180],"class_list":["post-80058","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-mac","tag-macbookair","tag-macbookpro"],"_links":{"self":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts\/80058","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/comments?post=80058"}],"version-history":[{"count":0,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts\/80058\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/media\/80059"}],"wp:attachment":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/media?parent=80058"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/categories?post=80058"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/tags?post=80058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
